TTM Shuntopac® 20-200 VÅK
Shunt unit for combined shunt units
TTM Shuntopac® VÅK is a combined shunt unit for both heat recovery and cooling to a ventilation system. The heat exchanger in the supply air is used in the winter case to transfer heat from the exhaust air and in the summer case to transfer cooling. The traditional heat exchanger is removed as cooling is transferred via a plate heat exchanger in the shunt unit’s supply air circuit.
TTM Shuntopac® VÅK is supplied in dimensions DN 20 up to DN 200 with each circuit adapted for the current flow.
TTM Shuntopac® 20-200 VÅK is supplied with 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.
