System divider with heat exchanger

Flexible shunt unit for heating or cooling

Shuntopac® 20-200 VÅVK

Shunt unit for heat recovery – Heating – Cooling

TTM Shuntopac® 20-200 VÅVK is a combined shunt unit for heat recovery, heating and cooling to a ventilation system. The heat exchanger in the supply air is used in the winter case to transfer heat both from the exhaust air and the heating primary side circuit and in the summer case to transfer cooling from the cooling media circuit. The traditional heating and cooling heat exchangers are removed as the heating and cooling is transferred via a plate heat exchanger in the shunt unit’s supply air circuit.

TTM Shuntopac® 20-200 VÅVK is supplied in dimensions DN 20 up to DN 200 with each circuit adapted for the current flow.

Shuntopac® 20-200 VÅVK 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.
