Heaters
VERSATILE EXTENDED LENGTH DIGITALLY CONTROLLED HEATER
The MaxiLimpetTM is a heater with built-in digital control and comes in various formats and extended lengths.
A popular model is the twin heater version with built-in dual control separate PID loops using digital electronics embedded inside and an adjustable, military-grade, waterproof external potentiometer. This can be combined with two 'Omega' rings to form the Twin Omega-Maxi model. This is often used for heating valves with dual flanges and provides a strong heat throughput to keep valves at a consistent temperature in all weathers.
The MaxiLimpet gives clear indication of operation using a status LED at one end, which will show proper power up function, alarms and show the power ON/OFF cycle pumping heat into the system.

Microprocessor Accuracy
Single or Twin control using a built in, sealed microprocessor
Adjustable
Simple setpoint adjustment by use of a dial on the end of the MaxiLimpet
Various Applications
Can be used on large valves, pinch valves, flat plates etc.
High Performance
Successfully used in Russia in -40C ambients and can go as high as 80°C with full adjustability
MaxiLimpet in Action
The top image to the right shows the Twin Omega-Maxi model being used with two independent control loops and two separate internal heaters linked with 'Omega'-style flange adapters.
The arrangement is fitted to a pinch valve, which contains a neoprene tube that is operated by fluid pressure. At low temperatures, the neoprene loses its flexibility, so that the valve becomes inoperable. The Limpet heating system is therefore designed to start operating when the temperature falls below a pre-determined level to ensure that the valve continues to operate correctly.
You can see that the two Omega shapes conduct heat around the valve flanges and into the aluminium valve body, ensuring that the valve remains operational. Of course, the valve is insulated to minimise heat loss.
Since each Omega has a separate control circuit, all set from one adjustable potentiometer, the orientation can be horizontal or vertical and the effects of thermal heat rise or differing thermal loads at each end of the valve will be compensated for automatically.
Heating this way is far superior to electrical trace heating as it provides a solid, mechanical, close-fitting arrangement that is very easy to fit with just a few bolts and a flex connection and will last a lifetime, giving you peace of mind.
The ability to work in ambient temperatures as low as -40°C means that the toughest of environments can be accommodated.
