System divider with heat exchanger
Flexible shunt unit for heating or cooling
Combined shunt units
TTM Shuntopac® 20-200 KV / KV Bypass is a combined shunt unit for both cooling and heating to a ventilation system.
The cooling heat exchanger is used to transfer both cooling and heating to the ventilation air. The traditional heat exchanger is removed as heat is transferred via a plate exchanger in the shunt unit’s secondary circuit.
TTM Shuntopac® 20-200 KV/KV Bypass is supplied with a fire and corrosion-proof housing in aluzinc sheet. Standard insulation is AF/Armaflex AF-2.
The shunt unit is environmentally approved.
Equipment TTM Shuntopac® KV
1. Control valve
2 pcs seat valves in a choice of make and type.
2. Adjustment valves
