For optimum performance and to maximize service life there are key factors that need to be considered before selecting an immersion heater. Abstract Electric immersion heaters are often used in water tanks for freeze protection or to maintain elevated process temperature and in oil tanks to maintain proper viscosity. Because the elements are fully immersed,…
Finding a cabinet enclosure heater does not have to be a game of “trial and error.” The importance of protecting your electronics isn’t something you should mess around with. An improperly sized cabinet enclosure heater can damage your electrical components and cost you in repairs. Depending on what’s in the cabinet, it can cause larger…
The Challenge To design a circulation heater that can heat up a varying mixtures of nitrogen and hydrogen gas at varying temperatures. With the varying mixture of gases the ability to transfer heat effectively changes. While Nitrogen is a very stable gas, hydrogen is a highly combustible gas with an auto ignition point of 997°F…
Application To heat jet fuel in an airline delivery vessel to keep it from freezing. Customer Requirements Pipe thread construction, fit into the existing design, thermostat controlled and must be explosion-proof. Problem The potential customer had recently received a large price increase for their vendor. The customer was already using a competitor’s pipe thread equivalent…
Abstract Seasonally shutting down a cooling tower by draining the tower is often not possible for three reasons: (1) In large buildings, the central core must often be cooled, even in sub-freezing weather (2) in sections of the United States, the occasional warm winter day necessitates sporadic air conditioning operation and (3) year-round one or…
Problem: Heating oil to 130°F with a flow rate of 400,000 lbs/hr, 1300 psig and an operating pressure of 800 psig. Solution: Considering the extreme flow rate the KW requirement was significant at 800 KW. Heatrex split the requirement between (2) 18″ – 400 KW circulation heaters. With the high pressure in mind 600 #…
A universal-style, 850°F electrically heated oven has work space dimensions measuring 36 inches wide x 36 inches deep x 36 inches high. The oven chamber is heated by Incoloy-sheathed tubular elements, while a 600-CFM, 0.5-HP recirculating blower provides front-to-rear universal airflow to the workload. The oven features 6-inch insulated walls, an aluminized steel exterior and…
The Challenge Mercury is in a lot of byproducts of flue-gas emissions from industrial production. Since mercury is extremely poisonous every effort to remove it from processes is needed to keep our environment safe. The Solution Heatrex is able to produce industrial finned tubular process air heaters that heat the carbon to improve its absorption…
