TTM Shuntopac® 20-200 VÅV
Shunt unit for combined shunt units
TTM Shuntopac® 20-200 VÅV is a combined shunt unit for both heat recovery and heating to a ventilation system.
The heat exchanger in the supply air is used to transfer heat both from the exhaust air and the heating primary side circuit. The traditional heat exchanger is removed as heat is transferred via a plate exchanger in the shunt unit’s supply air circuit.
TTM Shuntopac® 20-200 VÅV is supplied in dimensions DN 20 up to DN 200 with each circuit adapted for the current flow.
TTM Shuntopac® 20-200 VÅV is supplied with a fire and corrosion-proof housing in aluzinc sheet. Standard insulation is AF/Armaflex AF-4. The shunt unit has a stand with two legs and foot plates for floor set-up and attachment.
The standard version pipe package consists of fully-welded pressure vessel pipe SS-EN 10216-2, rustproofed with grey primer. Pipe packages in other qualities or with another surface treatment can be supplied to order.
The shunt unit is environmentally approved.
