Compact Heat Transfer Solution
Potable and process water heating system
The Spirax EasiHeatTM DHW incorporating SIMS technology is a complete, compact system for accurate heating of potable hot water or
hot water for process. These systems can be sized for any heating duty from 50 kW to approximately 1.1 MW and are supplied fully
assembled and pressure tested ready for installation.
The standard Spirax EasiHeatTM system is expandable by the inclusion of additional items such as steam pressure reduction, safety valve
and safety high limit shut-off should be selected separately.

Heat exchanger
One of the components that guarantees system
performance is the heat exchanger, which is precisely
engineered to match the specific duty requirements.
With a high efficiency and low volume to pressure ratio.
The plate and frame heat exchanger ensures reduced
inspection requirements whilst being fully maintainable
and expandable.
Temperature control
The steam flowrate is modulated to exactly match the heat
demand. The control valve is pneumatically or electrically
actuated and the system uses a fast response Pt100
temperature sensor and PLC controller for precise control.
The system can incorporate an energy monitoring system to
measure energy usage.
Metering
A key component guaranteeing accurate measurement of
energy usage, CO
2
emissions and cost control. The TVA
flowmeter is specifically designed for large turndown on
steam applications.
Condensate management
Spirax Sarco’s range of combined mechanical fluid pump
and steam trap units provide the total solution to all stall
conditions, by removing condensate under all operating
conditions.
