Heat transfer packages for heating systems, heat supply and DHW systems HTG series

Heat transfer package HTG series designed to heat water by saturated steam injections using a buffer tank with subsequent use in heating systems or hot water systems. The unit functionality can be extended by using additional units – CIRC pumping groups, PR pressure reduction groups and others. Heat transfer packages are available in the wattage range from 50 to 1500 kW and are fully assembled, tested and ready for use.

Heat transfer package consists of the following parts:

heat exchanger (finned, fin-and-tube or shell-and-tube type);
electric or pneumatic shut-off ball valve;
electric or pneumatic control with a valve positioner;
condensate drain unit;
stop valves;
control panel;
temperature sensors;
flow switch, safety thermostat;
control instruments.

The heat transfer package is fully automated and does not require a continuous presence of service staff
