Typical specification The heating system shall be a Spirax EasiHeat TM 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. In order to meet EU standards for Temperature Control Devices and Temperature Limiters For Heat Generating Systems, the selection of Independent High Limit (IHL) control is a compulsory selection for packages installed within the EU. 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.
