TH-500ZX Zero Flash Water Heater

Accepts Up to 150 psig Steam and Eliminates All Flash Steam and Subcools the Condensate
This eliminates those large steam pressure reducing valve stations and saves up to 40% over conventional installations. The JVV electronic control valve controls both temperature and steam pressure in the shell without pneumatics. The EC1000 UL Listed Touchscreen controller slowly ramps up the temperature eliminating water hammer and thermal shock on all applications. The additional Thermaflo BVV steam safety shutdown valve installed on the steam inlet adds an extra measure of safety to the Zero Flash when used with high steam supply systems. Safety relief valves set at 15 psig can be installed on any Zero Flash system shell when required. Consult us for higher inlet steam pressure applications.

Saves Energy Eliminating Flash Steam to Atmosphere
The TH-500ZX fully condenses the latent heat BTUs with its unique inner baffle and cross flow design, then discharges subcooled condensate below 200F eliminating all flash steam. Steam quality is conditioned to 100% as it flows into the shell futhur increasing the overall efficiency of the Zero Flash. In many applications the condensate temperature is well below 212F which utilizes the sensible heat BTUS of the condensate providing additional overall steam savings. No additional flash tanks, or roof vent holes are required, and condensate can be discharged directly to an electric or pressure powered condensate return pump system. Up to 10% of the steam can be saved over standard shell and tube systems.

Fully Electronic Integrated & Hydronic System Compatible
The TH-500ZX EC1000 Electronic Controller interfaces with BACNET, and many other BMS protocols so that temperature can be reset, remote start, and feedback points are available to the user. The Zero Flash EC1000 controls the outlet water temperature (adjustable) and the pressure in the heat exchanger shell simultaneously. A optional PID hydronic pumping program with the EC1000 controls hydronic loop pump VFD drives to sequence the pumps, alternate operation and provide pumping system feed back to the BMS system. This feature also applies to domestic water circulation systems.

Complete Engineered and Piped System

The TH500ZX is shipped completely piped, wired and tested to the customer. Thermaflo preforms actual steam and fluid “Factory Authorized Testing” before shipment using our factory on site boiler plant. This ensures a onsite startup with ease in the field.

Domestic Water or Hydronic Steam Water Heating Systems

The TH500ZX can be used for domestic water heating and is furnished with double wall condensing tube bundle and 316 stainless steel head and tube side materials. Standard single wall condensing tube bundles, and carbon steel materials are used for hydronic systems. Let your trained and certified Thermaflo manufacturers representative assist with your application.
