0 to 15 PSI Pneuchange Unit c/w Integrated Battery Alarm

 

The Pneuchange Change Over unit was developed specifically for use with CO2 and other gas dependent incubators although it is now used in many other applications. Since it's introduction it has become the unit of choice in thousands of laboratories world-wide. Pneuchange is recommended and supplied by most European incubator manufacturers and distributors and is compatible with all makes of incubator.

Pneuchange operates on a unique pneumatic logic principle requiring no electrical supply except for a battery to operate the change-over alarm. It can be placed anywhere in the gas supply line between the cylinder regulators and the incubator, either free sanding or fixed to a wall using the keyholes on the back of the unit. Inlet pressure gauges indicate the status of the gas cylinders and coloured indicators show which one is active. An outlet pressure regulator and gauge facilitate precise outlet pressure adjustment to the equipment. On depletion of a cylinder the unit automatically feeds from the alternative cylinder with no disruption of supply. Exhausted cylinders can be replaced at leisure. The unit requires no manual reset.

Inlet and outlet ports are 3/8”BSP threaded to accommodate a range of hose-tails to fit the supply tubing. Adaptors for other types of connection are also available.
