TTM NoXygen® F650 Degasser

Removes harmful gases in hydronic systems down to -10 °C

TTM NoXygen® F650 is a fully automatic vacuum degasser for heating and cooling systems. TTM NoXygen® F650 is designed for systems subjected to sub-zero temperatures. Energy losses, corrosion and sound problems in the systems are mainly caused by a high gas concentration in the system fluid.

In the air conditioning unit, overheating and undercooling are affected by high gas concentrations in the fluid.

TTM NoXygen® F650 prevents above stated problems by using an effective method that keeps the system free of gases that gives higher energy efficiency, lower maintenance cost and longer lifetime of the system components.

TTM NoXygen® F650 can be installed in both existing and new systems. TTM NoXygen® F650 is specially designed for large kitchens, ice rinks, comfort cooling, commercial cooling and similar facilities.

TTM NoXygen® F650 is environmentally assessed according to a Swedish Standard.

TTM NoXygen® takes out and treats a partial stream that is pumped from the main fluid conduit and processed with a strong underpressure in the NoXygen unit between -0.7 and -0.9 bars. The gases are released by the pressure reduction and are led out through a gas-release valve. The fluid is then returned to the main conduit.

TTM NoXygen® is very easy to install, commission and operate. Operation is monitored by a control unit where 2 pushes of a button is enough to start the operating mode.

TTM NoXygen® starts in manual operation and after 30 days it automatically switch to a timer mode.

There is an option to select manual operation between 1-30 days before. TTM NoXygen® switches over to timer operation. Time operation can be selected using three different starting times: 9:00 am, 1:00 pm or 7:00 pm. In most cases, one hour of operation per day is fully sufficient to keep the gas concentration in the fluid at a low level. Timer operation can be chosen for operating times of 1-8 hours.
