Removes harmful gases in hydronic systems and automatically refills the system with water
TTM NoXygen® M650 is a fully automatic vacuum degasser for heating and cooling systems that can be connected for control, regulation and monitoring via Modbus RTU. Energy losses, corrosion and sound problems in the systems are mainly caused by a high gas concentration in the system fluid.
TTM NoXygen® M650 is provided with an automatic water-refilling system. When the gases are eliminated by degassing the hydronic system, the system pressure decreases, and the unit automatically refills the system with dilution water until the pre-set system pressure is obtained. The displays on the unit how much water that has been filled into the system.
TTM NoXygen® M650 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® can be installed in both existing and new systems.
TTM NoXygen® is environmentally assessed according to a Swedish Standard.

Operating principle
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® M650 is provided with an automatic water-filling system that compensates for the reduction in volume that occurs when removing gasses. The filling of dilution water occurs automatically when the pressure in the device falls below the set reference value. As a safety measure, NoXygen will emit an alarm signal upon each refilling as an indication that that water is being introduced into the system.
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.

The purpose of liquid treatment by vacuum degassing is to reduce the gas content to a level where corrosion stops and the system liquid regains its optimum energy-carrying properties.

Simonsland in Borås
When Kanico created a new district in the town of Borås, they chose TTM to supply shunt units for the HVAC systems. The area is called Simonsland and contains 60,000 m2 of buildings.
TTM Energiprodukter was one of the suppliers in the construction of the prestigious Copenhagen Opera House Together with their reseller, the company succeeded in winning the deal and delivering 98 different shunt units.
NCC are building their new head office at Järva Krog in Solna. The new head office has a strategic and easily accessible position adjacent to the E4 motorway.
