A family of microprocessor controlled plug & play IP rated process equipment heaters for valves, pumps, flowmeters, plates and other equipment.
Introducing the AlphaLimpet
The AlphaLimpet is a microprocessor controlled dual channel heater that is designed to provide high heat flow to process equipment.

It is a superior alternative to trace-heating and jacketed water heated systems.
Microprocessor Accuracy
The AlphaLimpet incorporates a microprocessor built within the heater block, giving the heater the ability to control temperature based upon an internal, user-adjustable set-point using pre-set PID parameters. This built-in high performance system achieves all this without a control panel.
Single or dual temperature setpoint, ramp rate and various mode setting are included as standard within the unit.
Ramp Control
Set ramp 'on' or 'off' and between 1 to 99°C per minute to assist where shock temperatures may damage your product.

The user can monitor the heater’s status using a simple linked-together healthy signal. This is often critical for users and no other known system provides a single, self-contained heating block with such flexibility and reporting ability without hooking on an external control system, i.e., there is no need for a control panel.

Key Features
  • Accurate temperature control

  • Programmable features and external unit control

  • Control modes built-in for different applications

  • Monitored heater status using a simple linked-together healthy signal

If desired, the user can wire up Limpets in a combination of Primary / Secondary (either internally or externally controlled) and can even stagger set points to generate a gradient heat profile on the workpiece that is being heated.
Different Modes
A Limpet can also be used in “Primary” or “Secondary” mode, so that an AlphaLimpet, being controlled either by an internal setpoint or an external ON/OFF signal, can drive a series of secondary heaters (either BetaLimpets or MicroLimpets) from the same connection.
Heat Transfer
Unless it can be mounted onto a flat surface, a Limpet must normally be used in combination with a profiled adapter block, which gives a direct heat flow path to the workpiece shape, hence being able to heat a myriad of equipment surfaces by the use of a correctly-profiled metal adapter block (usually aluminium).

The adapter block also serves as an effective heat storage device, thereby enhancing the mass of heat flow into the workpiece under varying cooling loads. We make a range of standard adaptor blocks that will fit most common items and radii but we can also produce custom-profiled blocks, as required.

The blocks are usually fitted to the workpiece with stainless steel adjustable straps and the Limpet is fitted to the adapter block using easy to fit T-nuts.
Typical AlphaLimpet in action. The GA4425 Lobe pump from Wright Flow Technologies gets fitted in quick time with the a step-up plate and a heating plate before the AlphaLimpet is fitted.  Simple, clean, dry and effective. See the BestPump story below.

Limpet fits to most process pumps with an adapter block to apply controlled heat where needed

Metal Pipes

With the use of an Omega shaped adapter ring, we can attach to valves to ensure they run trouble free.


Flow meters can be particularly difficult to heat when using viscous products in batch processes. The AlphaLimpet is designed for just this type of problem.
