WESPC 145206120 145206170 145206180 145206181 145206182 Thermostat for Perkins

Application:

WESPC thermostats 145206120, 145206170, 145206180, 145206181, and 145206182 are designed for Perkins 100 and 400 series 2-, 3-, and 4-cylinder diesel engines, including models 103-15, 104-19, 104-22, 403C-15, 403C-17, 404C-22, and 404C-22T. These thermostats regulate coolant flow based on engine temperature, ensuring rapid warm-up and maintaining thermal stability during operation. They begin to open at 82°C (180°F) and reach full open position approximately 15–20°F above their rated temperature. These components are essential for protecting the engine from overheating and supporting consistent performance across various applications.

Generator sets:

Commonly installed in 10–40 kVA diesel generator platforms powered by Perkins 403C, 403C-17, and 404C-22 engines. WESPC thermostats maintain stable coolant circulation during continuous operation, contributing to fuel efficiency and reduced wear. Verified applications include FG Wilson models such as P10P2S, P13.5-4, P14E2S, and P16.5P2, where thermal control is critical to uptime and combustion stability.

onstruction machinery:

Widely used in JCB, Volvo CE, and Takeuchi compact equipment powered by Perkins 100 and 400 series engines. The thermostats ensure optimal engine temperature in high-vibration environments, supporting torque output and mechanical reliability. Verified applications include JCB Robot 160, 170, 180, 802.7Z, 8030ZTS, 8045ZTS, and Takeuchi TW50 loaders, where thermal regulation is essential for off-road performance.

Agricultural equipment:

Applied in small tractors and utility vehicles requiring compact diesel power units. WESPC thermostats support rapid warm-up and consistent temperature regulation during extended field operations, reducing fuel consumption and minimizing engine stress. They are suitable for Case IH Farmall 31–50 series and Massey Ferguson compact tractors equipped with Perkins 103-15 and 104-22 engines.

Industrial systems:

Installed in stationary pumps, hydraulic power units, and mechanical drives using Perkins 100 and 400 series engines. The thermostats support continuous operation by regulating coolant flow and maintaining lubrication integrity. Their precise thermal response helps prevent thermal cycling and component fatigue in demanding industrial environments with variable load demands.
