Why Econoliser

Immersion Steriliser Problems

“A compliant steriliser must provide clean water at the correct temperature every time.”

Immersion sterilisers protect against cross-contamination only while their water stays at or above the critical 82°C threshold and is clean. A shift away from continuous flow, made to save water and energy, results in a problematic cycle of temperature drops or contamination.

If the water is below 82 °C, the steriliser cannot be compliant

/ PROBLEM → SOLUTION

Where it fails, and how the Econoliser fixes it

  1. 1
    The problem

    Continuous flow

    Keeps the steriliser clean and at temperature — but this uses as much as 3 litres per minute, per steriliser.

    3 L / minHigh water use

    Econoliser solution

    Timed spray, not constant flow

    The timed spray, always above 82 °C, massively cuts water and energy consumption — one customer recorded 91% savings.

    0.14 L / cycle≈90% less water

  2. 2
    The problem

    Refresh left to the operative

    Switching to occasional refresh leaves the decision to the operative — which does not satisfy HACCP.

    Non-compliant

    Econoliser solution

    No standing water to refresh

    Placing a knife or tool in the Econoliser triggers the spray automatically, so operatives don’t have to manage refresh.

  3. 3
    The problem

    Feed water below temperature

    If inlet water is <82 °C, this cannot instantaneously be heated to ≥82 °C. This is non-compliant until the correct temperature is reached.

    Non-compliant

    Econoliser solution

    Heats its own water

    The Econoliser makes its own hot water and runs even on a cold feed (45 °C is optimal) — no need to produce 90 °C water centrally.

    Always above 82 °CNo central 90 °C supply

  4. 4
    The problem

    Low-cost thermostats

    Thermostats suffer from hysteresis and can’t hold temperature — water temperature can drop below ≥82 °C before the heating element is triggered.

    Non-compliant

    Econoliser solution

    Microprocessor-controlled heat

    A microprocessor and two temperature sensors hold a constant supply of 90 °C water, so it never drifts below the line.

    Always at temperatureAlways compliant

  5. 5
    The problem

    Dirty standing water

    Inconsistent refresh lets the standing water grow dirty, passing contamination between carcasses.

    Contamination

    Econoliser solution

    Flushed every cycle

    Dirty water is expelled after every sterilisation cycle, and there’s no standing water left to become contaminated.

    Zero build-upNo cross-contamination
