On-Board Thermal Management

Proven Reliability in Extreme Conditions

The continued drive towards lower NOx emissions has led to an increased use of Selective Catalytic Reduction (SCR) in off-highway applications. Incorporating SCR system hardware into off-road engines requires designs and packaging for a wide range of vehicles, including mobile equipment with operating life spans that often far exceed on-highway applications.
 

At Parker, we recognize that today’s SCR systems must remain dependable under severe operating conditions, temperatures, and harsh work environments. To help meet this challenge, we use our proven track record of success with on-road applications to develop products ideally suited for the demanding off-road market. SCR Coolant valves are suitable for many industrial applications:

  • Truck & Bus
  • Construction Equipment
  • Agricultural Machinery
  • Mining Vehicles
  • Rail & Transit Systems
  • Stationary Generators
  • Marine
