Configurable features All EasiHeat systems are designed for the required heat load with features to suit each application and requirement, the tables below describe the configurable features available. Safety features Feature Benefits Option
- Spirax Standard - European Standard EN14597 - Italy INAIL - None
High limit temperature control to ensure the system will automatically and safely shut down to prevent the risk of scalding should a problem occur A steam side pressure test using compressed air to prove the integrity of heat exchanger gaskets and plates from damage and risks associated with cross contamination. Requires TA31, PA31 and valve position feedback
Fail-safe High Limit
Integrity test including: - Steam supply failure alarm - Supply feedwater failure alarm - Sequenced shut down
Yes
No
Yes No (Mandatory for EL actuators when you don’t have independent high limit)
In the event of power outage, UPS will provide a safe sequenced shutdown of the EasiHeat system.
Uninterrupted Power Supply (UPS)
A range of local isolation options to support maintenance procedures and processes
Additional manual steam isolation
On request
Advanced control features Control features are displayed locally on the PLC or via communications protocol into existing control systems. Feature Benefits Option Forward Control – Thermal, including: - Sequenced shut down - Undersized alarm Monitors the return water temperature and initiates PID changes to reduce the risk of system shutdown from high temperature overshoot. Requires TA11 Yes No
