Typical specification

The potable and process water system shall be a Spirax EasiHeatTM compact heat transfer system complete with PLC functionality and

SIMS technology to provide energy monitoring and remote access. The system will be pre-assembled and mounted on a compact frame

with either pneumatic or electric control option.

How to order

All systems are designed for the required heat load with controls to suit the application. The best way of ensuring that we have all the

necessary information for quotation and manufacture is to complete our enquiry data sheet. Copies can be supplied on request and

special requirements should be detailed.
