SR882 EPP Solar Work Station & Pump Stations

1.1 Overview

• SR882 EPP dual-line solar workstation is used in a split-pressure solar water heater system.

• It combines flow control, heat cycle, exhaust, pressure control, temperature display, system injection/discharge and many other functions into one.
• By connecting solar collectors and split pressurized water tanks,store solar energy in a water tank.It can monitor system temperature, pressure, flow, etc. at any time.
• It has SD card storage function.
