This is a CPRU CNG pressure reduction module with integrated heating (6kw). Comes with temperature probe for J type thermal couple input for a temperature controller. The outputs of the temperature controller operate a relay which engage the load power to the heaters. This unit is designed in two stages and is mechanically set to the desired output pressure (adjustable all the way down to 30psi) maximum pressure input is 4500 psi. I will include the setup manual and all data sheets in the shipment. This is a plug and play module for reducing CNG pressure and operating (150kw gas generator). Flow range can easily handle 100 scfm using all 4 heaters during the flow operation
