What could your business gain from investing in Tenselo?

If you run a busy shop, think fewer callbacks. If you design systems, think more time for design decisions and client advice. If you manage a team, think confident staff with the tools to help customers and make more time for sales.

Your return starts with the time you save searching catalogues, calling suppliers and repeating calculations. At an example staff cost of A$40 an hour, saving two hours a month would free up A$80 worth of time, more than the A$69 Basic subscription.

What would that time be worth to your business? Compare the monthly plans below and see how much time you would need to save to cover the cost.

Your tools at your fingertips. Tenselo works in a web browser on phones and tablets, including iPhones and iPads, as well as laptops and desktop computers. With internet access, use your account in the shop, at your desk or onsite talking with a customer.

Built to be one of a kind. Built in Australia.

Tenselo brings pump selection, irrigation, water treatment, pipe hydraulics, electrical calculations, supplier information and professional reports together in one platform. It gives pump and irrigation retailers, designers, consultants, water-treatment specialists, aquaculture operators and civil water professionals practical tools for the work in front of them.

From an old pump on the counter to a treatment assessment or an irrigation design onsite, give your team the tools to work through the job, explain the options and prepare a quote or professional report.

Illustrative scenario

Bill has a customer waiting and a shop to run

It is a busy morning at Bill’s pump shop. The phone is ringing, another customer is waiting at the counter, and a farmer asks, “What size pump will I need for my new centre pivot?”

Without the right tools, Bill could spend one or two hours searching through old, dusty catalogues or calling suppliers to work out the pump requirements for him, all while trying to serve other customers. The enquiry gets interrupted, and the farmer is left waiting for a callback.

In this scenario, the farmer has the pivot’s flow and pressure requirements, along with the necessary site and pipework details. Bill opens Tenselo and works through an initial sizing in a few minutes. Whether the customer is in the shop or on the phone, Bill can discuss the estimated pump flow and head right there and then. Before recommending a pump, he checks the site assumptions and the manufacturer’s pump curve.

What does Bill gain?

Bill keeps the enquiry moving while he has the customer’s attention. Less time searching catalogues and chasing callbacks means more time to discuss the options, prepare a quote and serve the next customer, with fewer enquiries left unfinished when the shop closes.

If Tenselo helped you handle enquiries like this, how much would that time be worth to your business?

Another illustrative scenario

“Can I use my bore water in the house, and is it worth treating?”

Another customer walks into Bill’s pump shop with a laboratory water analysis. They want to use their bore water in the house, but do not know what treatment they need or whether it will be worth the expense.

With the report and the household’s water requirements in front of him, Bill can work through three steps with Tenselo:

  1. 1. Understand the water. Bill enters the test results and units, confirms how the water will be used, and reviews the findings and any missing tests.
  2. 2. Work through the treatment options. Does the customer need a water softener? If the analysis points to softening, Bill uses Tenselo to size it for the household’s hardness, water use and flow requirements. Where a matching model is available from his selected suppliers, Tenselo provides a model reference he can check and price. He also reviews any other treatment needed, such as iron removal before the softener.
  3. 3. Decide whether it is worth pursuing. Using the results alongside equipment and installation quotes, Bill can discuss running costs, maintenance and water use with the customer, and compare treatment with an alternative water supply.

Bill can give the customer a preliminary recommendation and explain whether treatment looks practical and worth pursuing, or whether more testing or another supply is the better next step. The customer leaves with a clearer direction before spending money on equipment.

Household water suitability needs appropriate testing and specialist review. The calculation does not certify drinking-water safety; treatment performance must be confirmed before use.

The value for Bill: a more useful conversation at the counter, a clearer basis for a quote and a customer who understands the next step.

Illustrative scenario · Pump replacement

An old Grundfos on the counter. A Davey on Bill’s shelf.

A customer drops an old Grundfos CH2-50 on the counter. “Can you replace this?” Bill sells Davey pumps and has HM-series models in stock. He wants to find a suitable replacement from the range he carries while the customer is still in the shop.

Bill selects the Grundfos CH2-50, chooses Davey HM as the replacement range and switches on the pump-curve display. In a worked run of Tenselo’s Domestic Pump Match calculator, the closest Davey HM candidate was the HM60-06, rated an approximate curve match. Bill now has a specific model to check against his shelf stock and price.

Bill can show the customer both models on the same pump-curve chart: the old Grundfos CH2-50 and the proposed Davey HM60-06. At the example’s representative flow of 36 L/min, the calculator shows 29.2 m head for the modelled old pump and 37.8 m for the Davey, a difference of 8.6 m. He can explain that difference while they look at the curves together.

The worked result is an approximate match, and DOM-002 is currently marked provisional pending independent revalidation. The old Grundfos curve is modelled from legacy data. Before quoting the HM60-06 as a suitable replacement, Bill checks the required flow and pressure, manufacturer’s curve, power supply, suction conditions, connections and controls.

The value for Bill: a model reference to investigate and price, a visual comparison he can explain to the customer and a clearer path from enquiry to a suitable replacement sale.

Illustrative scenario · Onsite with a client

“What size mainline do I need here?”

Answers at your fingertips. Sales staff and consultants can use Tenselo on their phones while onsite talking with a customer. With internet access and their own authorised accounts, they can work through sizing questions, compare options and explain the results as the conversation happens.

One of Bill’s staff is walking a proposed irrigation mainline with a client. The client wants to discuss pipe sizes before committing to the job. With internet access, the staff member opens Tenselo in their phone’s browser and signs in to their own authorised account.

Using the required flow, pipe length and material, elevation change and pressure requirements, they work through a preliminary mainline size and check friction loss. They can compare options with the client there and then, and explain how the pipe choice affects the pressure available and the pump duty.

Any measurements or site details still to confirm are recorded for the final design. The conversation can move towards an informed quote while everyone is looking at the same job.

The value for the team: useful sizing tools on their phones, more productive site visits and fewer questions left waiting until they return to the shop.

Motivate your staff. Give them the tools to succeed.

Give your staff a way to work through customer questions with confidence. Less time hunting for information can mean less frustration and more satisfaction in helping a customer move forward.

Put that time into quotes, customer service and sales. When your team uses the time saved to win more work or reduce the cost of handling each enquiry, it can help improve your profit.

What is Tenselo?

Tenselo is an Australian water-engineering calculator suite for irrigation, pumping, water treatment, aquaculture, civil hydraulics and electrical work. It covers calculators organised by engineering discipline, and every result comes with a plain-English answer and a branded PDF report.

Who is it for?

Irrigation designers, pump and irrigation retailers, water treatment specialists, aquaculture operators, civil and hydraulic consultants, and the people on the counter who have to answer a customer's question quickly and correctly.

Can I use it now?

Apply for access and tell us about your business. Once approved, verify your email and set your password to sign in. Each person needs their own account.

What does it cost?

Single-industry plans start at A$69 per month and the Complete Library is A$249 per month, with annual billing at ten months for twelve: two months free, saving 16.7% compared with twelve monthly payments. Business Team is shown at A$599 per month; enterprise options are priced on application. Prices include GST. Confirm your selected billing interval and total before subscribing.

Which standards does it follow?

Methods are aligned to AS/NZS standards and recognised industry references, with manufacturer data taken from published datasheets. Every result shows the method and assumptions it used so the work can be checked.

Does it name real products?

Yes. Selector calculators pick from real supplier catalogues and name the model, pipe class or dose rate. Tenselo only ever names a brand you have asked it to consider, and every selection carries a note to confirm the exact model and trim with the manufacturer before ordering.

Is it Australian?

Yes. Tenselo is built in Australia for Australian and New Zealand practice, including local climate data, standards and supplier catalogues.

Can I cancel my Tenselo subscription at any time?

Yes. You can cancel a monthly or annual Tenselo subscription at any time. Cancellation stops future renewals, and access continues until the end of the period you have already paid for. For an annual subscription, that means the end of the prepaid annual period. Enterprise agreements follow their own written terms.

How do I cancel my subscription?

To request cancellation, email sales@tenselo.com.au from your account email address and tell us you want to stop your subscription renewing. Include the account or company name so we can identify the subscription. Contact us at the same address if you cannot sign in or need help with billing.

What happens if I want a refund for unused time?

Cancellation stops renewal; it is not confirmation that a refund has been approved. For a refund request or a question about unused prepaid time, email sales@tenselo.com.au. If something is not right, please contact us within 14 days of the charge and we will work with you in good faith, as set out in the Refund Policy. Enterprise agreements follow their own written terms. This contact timeframe does not limit your rights under applicable consumer law, including the Australian Consumer Law.
