the ME6S140 is ideal for suction line service because it only requires a low pressure differential (1 psi) to open fully and maintain flow

as the orifice is bored for a higher refrigerant mass flow rate

5 Amp circuit

this is a universal HVAC relay for any 120V application requiring similar amperage and terminal configurations

McDonnell & Miller 94-7B-HD Controller 318423-701 the ME6S140 is ideal forThe McDonnell & Miller 94 7B HD is a high performance head mechanism only designed for heavy duty commercial and industrial steam applications. As a critical replacement head mechanism for Series 94 and 194 controllers, this unit integrates a combination low water cut off and pump controller to maintain precise boiler water level control. Engineered for systems with a maximum pressure of 250 PSI, it utilizes a 7B potentiometer switch to provide a 135
