Our Advanced Engineering and Test group operates the H.G. Runnings Technical Center in Seattle, a hub of innovation and research in heat transfer, refrigerant management, diagnostics, and control systems for heavy-duty vehicles and equipment.
In addition to evaluating Red Dot concepts and products, the H.G. Runnings Technical Center is available for independent research and product validation.
At 48 feet long, 18 feet high, and 18 feet wide, our environmental chamber is big enough to accommodate a full-sized truck, loader, or other heavy vehicle. The chamber can produce an air temperature range of -20 F to 140 F with relative humidity from 20% to 95%. We can instrument the vehicle with pressure transducers, hook up a dynamometer, build up engine heat and hydraulic loads—all in an effort to fine-tune A/C performance.
Provides precise simulation of a wide range of under-hood and in-cab conditions. Twenty system parameters are controlled to within a 1% tolerance. Sixty data points are collected at a rate of up to four times per second.
Our LDS V875-640 Electrodynamic Shaker is used for testing components, subassemblies, and complete heater and A/C systems, as well as to validate components from outside suppliers.
For prolonged evaluation of fans and blower motors to validate stated hour ratings and standards for reliability, quality, and performance.
Decibel levels and frequencies generated by blower motors and other components can be used to define acceptance criteria for noise and to assure that products meet customer standards for Noise, Vibration, and Harshness (NVH).
Measures radiated and conducted electronic emissions and potential interference inside the cab. Used to pre-qualify product designs for MIL-STD-461E and commercial standards.
