Tube heaters.This four-page brochure describes low intensity infrared tube heaters ranging from 40,000 to 250,000 btu/ hr. The brochure describes the company's expanded line of ETS/ETU Series low-intensity infrared tube heaters, available in both natural and propane propane, CH3CH2CH3, colorless, gaseous alkane. It is readily liquefied by compression and cooling. It melts at −189.9°C; and boils at −42.2°C;. gas. The line is expanded to include 19 different heaters and more than 100 configurations. The expansion is said to enhance the company's capability to custom design a radiant heating radiant heating: see heating.
Heating system in which heat is transmitted by radiation from a heated surface. Radiant heating systems usually employ either electric-resistance wiring or hot-water heating pipes, which may embedded in system that meets precise facility requirements for optimum flexibility, economy and maximum energy efficiency.
