This construction ensures that the resistance wire temperatures are dissipated much more rapidly through the sheath than is possible with conventional cartridge construction. Since this fast rate of heat transler greally reduces the temperature difference between the resistance wire and sheath, itis possible for a ‘RED HOTROD' Unit to be operated at elevated temperatures without the resistance wire over-neating, These factors make it possible to provide concentrated heat in small in fact, as much as 24: time more heat than provided by a standacd unit by the same size.

The heat is transferred via invisible electromagnetic waves from an infra red energy source. When infra red energy strikes the product the radiation is absorbed and converted into heat. This radiant energy does not heat the air appreciably and requires no air for transmission. LOW INSTALLATION AND MAINTENANCE COSTS. The simplicity of infra red ovens and the lightness of their structure results in a low first cost and minimum maintenance, FAST HEAT-UP AND COOL-DOWN TIME. Because infra red ovens do not rely on air to transmit the heat, the oven starts to heat the product the moment it is energised. This reduces the oven operating time. Also, the oven quickly cools down after being de-energised. HIGH EFFICIENCY. Utilising high quality electric infra red heaters up to 86% of the energy input is converted into process heating radiation. CLEAN HEAT. Electric infra red radiants, themselves, do not produce products of combustion. Thus, the product is not contaminated by hot gas, there is no flame to contain and no product of combustion that must be discharged. SPACE SAVINGS. High heat source concentrations quickly increase product temperature, shorten conveyor length and ‘save floor area, Also, compact infra red ovens can be suspended from the ceiling. VERSATILITY. To increase output, infra red ovens can be added to existing ovens, or built into existing machines to increase output. MOBILITY. Units can be designed as portable or easily disassembled for moving with cost-saving plant changes not ‘as expensive in comparison to larger and heavier convection type ovens. CONVENIENT POWER SUPPLY. Electric power can be readily provided to any location in the plant. Also changes are simple and inexpensive.HELIOS RADIANT HEATERS RADIANT HEATERS Helios F.I.R, radiant heaters supply industsy’s need for robust, compact, and reliable source of infra red heat, which is in the invisible far-infra red wave length and is absorbed with almost equal speed by all colours and surfaces. Built-in reflectors radiate this heat in a wide uniform band, assuring even heating, therefore making these units ideal for many industrial uses. GENERAL APPLICATIONS.
