Custom Engineered Industrial Direct Inject Heating
Custom Engineered Direct Injection Temperature Control Systems. Tap into existing plant hot water or glycol to inject energy and meet the demands of your process operation.
DIW Series Custom-Engineered Industrial Direct Water/Water-Glycol Heating Systems offer Safe Reliable Performance in an industrial-grade system that takes advantage of your facility’s central heat source to precisely control temperatures in a specific secondary sub-loop of your process using the direct injection of water/water-glycol.
For use with available existing water/water-glycol central heating sources, DIW Series Temperature Control Units offer a better alternative for applications that require flow rates higher than available from the central system or that require precise temperature control and/or heating and cooling. DIW Series Systems are for use with available existing water/water-glycol central heating sources, with maximum operating temperatures up to 400°F, up to 600 Volt, 3-Phase, 50/60 Hz power capabilities, and heating capacities of up to 5 MM Btu/Hr. If an existing water/water-glycol central heating source is not available, combine with one of HEAT’s WG Series or GFW Series water/water-glycol systems to provide the necessary heating capacity needed.
Our engineering team will work with you to design a system based on your unique process or application. DIW Series systems typically include a Circulating Pump, Heating Circuit, Cooling Circuit, Expansion Tank, and Control Panel. These units are constructed with all-welded Carbon Steel or Stainless-Steel wetted materials, insulated with Non-Wicking Cellular Glass, Fiberglass, Rubber and Mineral Wool Insulation, and assembled on a drip-proof, seal-welded plate-and-channel fluid containment base.
HEAT offers four distinct levels of customization, ranging from minimal customization to fully built-to-specification designs. Each unique system undergoes a Factory Acceptance Test in accordance with HEAT standard practice prior to shipment.
