Coltri 450-550-650-750 ET Open threephasic Commercial Diving High Pressure Compressor: Open meets professional needs that require large charging capacities in hot, poorly ventilated or tropical countries. It is equipped with 4 front filling connections for high pressure hoses, an intuitive control panel and an electric motor. The pumping unit, chosen from the 4 most powerful, is exposed in the rear part of the structure to ensure a better cooling cycle. For longer filter life, the Tornado high pressure dryer is recommended
Coltri LP250 Nitrox ROTARY for Scuba Diving: It consists of an industrial screw compressor that delivers air at a pressure of 10 bar to the Parker® membrane. The percentage of oxygen obtained at the outlet can be adjusted from 32% to 36% thanks to a valve accessible on the front side of the compressor. If connected to a compressor with pumping unit 315 (MCH 16), Nitrox at 32% can be obtained up to a pressure of 232 bar. The oxygen analyzer allows you to check the correct percentage, adjusting it through the appropriate valve.
The Coltri LP300 Nitrox ROTARY model consists of an industrial screw compressor that delivers air at a pressure of 12 bar to a membrane that separates nitrogen and oxygen up to a maximum percentage of 40% O2. The enriched air can be compressed at a pressure of 232 bar in combination with a high pressure compressor. The percentage of oxygen obtained at the outlet can be regulated from 22.4% to 40% using a valve directly accessible on top of the compressor. The oxygen analyser allows checking of the correct percentage adjusted by means of the appropriate valve.
Dry sealed system suitable for cold water diving. Specially designed for technical diving first stage.No turret, 4 MP port 3/8 UNF, 1 HP port 7/16 UNF
At the top of the Nitrox line, the Coltri LP600 ROTARY system consists of an industrial screw compressor that delivers air at a pressure of 8 bar to a membrane that separates nitrogen and oxygen at atmospheric pressure until Nitrox 40% O2 is obtained and can be compressed at a pressure of 232 bar in combination with a high pressure compressor. The percentage of oxygen obtained at the outlet can be regulated from 22.4% to 40% using a valve directly accessible on top of the compressor. Exclusive to the the Heavy Duty line compressors.
It has two gauges (one for each pressure) for controlling the load pressure. With its internal pressure regulator, you have the ability to offer dual pressure load (2 outputs and 2 outputs 300 bar to 225 bar).
Apeks has developed unique first stages specifically for use on a twinset. The benefits of this system are that there is a minimised risk of accidental snagging, no hose kinking and easier access to the manifold valves. Each first stage has three medium pressure ports and one high pressure port. They are over-balanced, cold water compatible and extremely robust. TEK3 looks great too!
Panel loading with 4 exits for connection to any compressor Coltri range. It has manometer to control the load pressure. Combined with a bank of air, it can be an ideal place for a bottle loading station configuration.
