WESPC SE573 1 Thermostat for Perkins 400 1000 Series Diesel Engine Parts

Application:

WESPC SE573/1 thermostat assembly is designed for Perkins 4000 series 6-, 8-, 12-, and 16-cylinder diesel engines, including models 4006-TAG1, 4006-TAG2, 4008-TAG1, 4008-TAG2, 4012-TAG1, 4012-TAG2, 4016-TAG1, and 4016-TAG2. These high-capacity engines are widely used in large generator sets, marine propulsion systems, industrial power modules, and energy infrastructure requiring precise thermal regulation. The thermostat controls coolant flow based on engine temperature, ensuring rapid warm-up and maintaining thermal stability under continuous heavy-duty operation. It supports efficient heat dissipation, protects against overheating, and contributes to long-term engine reliability in high-output environments.

Generator sets:

Commonly installed in 500–2000 kVA diesel generator platforms powered by Perkins 4000 series engines. The WESPC SE573/1 thermostat ensures consistent coolant circulation during extended operation, supporting stable combustion and fuel efficiency. It helps prevent thermal stress and component fatigue in commercial standby systems, data center power modules, and utility-grade gensets operating under peak load conditions.

Construction machinery:

Suitable for large-scale equipment such as quarry crushers, mining excavators, and tunnel boring machines powered by Perkins 4012 and 4016 engines. The thermostat maintains optimal engine temperature in high-vibration, off-road environments, supporting torque output and mechanical integrity. It contributes to reduced wear and improved uptime in applications requiring sustained engine performance under variable terrain and load cycles.

Marine systems:

Applied in propulsion and auxiliary power units aboard commercial vessels, ferries, and offshore platforms using Perkins 4006, 4012, and 4016 engines. The WESPC SE573/1 thermostat supports continuous operation by regulating coolant flow and maintaining lubrication integrity. Its robust design ensures performance in saltwater environments with fluctuating ambient temperatures and high thermal loads.

Industrial systems:

Installed in stationary pumps, compressors, and mechanical drives requiring high engine stability and thermal precision. The thermostat supports continuous operation by maintaining coolant flow and preventing overheating. Its precise thermal response helps prevent thermal cycling and component fatigue in demanding industrial environments with frequent start-stop cycles and elevated ambient temperatures.
