Thông tin chi tiết

The Atlas Copco thermostat 1619733300 is a 40°C temperature-regulating element built for oil-injected rotary screw compressors . Inside the oil thermostatic valve, this small wax-filled cartridge decides how much oil flows through the cooler and how much bypasses it. Getting that balance right keeps the airend safe and the oil in good condition. It also keeps the whole machine inside its designed temperature window. This article explains what 1619733300 is and how it works. It also covers fitment, failure signs, and correct replacement.

What the 1619733300 Thermostat Is

The part number 1619733300 identifies a thermostat, not a complete valve. In Atlas Copco terminology a thermostat is the sensing and actuating core that sits inside the thermostatic valve body. The valve body, the housing, the ports and the bypass passage come as a separate assembly. The 1619733300 element is the part you fit inside it. Technicians often call it the thermostat cartridge, the thermostat valve core, or simply the 40°C wax element.

Although it is only a few centimetres long, 1619733300 carries a demanding job. It must open at a fixed setpoint, hold that setpoint across thousands of operating hours, and survive constant oil pressure and temperature cycling. The 40°C rating means the element begins to open near 40°C. It keeps modulating flow as the temperature rises further.

How the 1619733300 Thermostat Works

In an oil-injected screw compressor the lubrication oil does two jobs at once. It seals and cools the rotors, and it carries heat away from the compression process. After leaving the airend, the oil passes through the thermostatic valve, where 1619733300 makes the routing decision.

When the machine starts cold, the oil is below the 40°C setpoint. The wax element is contracted and the bypass stays closed. Most of the oil circulates back to the system without reaching the cooler. This lets the compressor reach working temperature quickly, which keeps the oil above the dew point and prevents water condensation inside the tank.

As the oil warms past 40°C, the wax inside 1619733300 expands and pushes the valve open, gradually directing oil through the cooler. More flow reaches the cooler as the oil gets hotter, so the outlet temperature settles into a stable band. The element never fully shuts or opens in one step. It modulates continuously, which is why a worn or sticky thermostat produces unstable temperatures.

The heart of 1619733300 is a sealed capsule filled with a wax and metal-dust mi
