SPACE HEATER

Space heaters provide heat source for air heating to maintain a desired temperature or to provide anti-condensation heating to keep moisture out. The space heaters are used in applications such as electric switch boards or panels, terminal box, instrument cabinets or enclosures.

DFINITI provides two types of space heater to meet the different needs of customers: Constant Power type and Self-regulating (PTC, Positive Temperature Coefficient) type. Our IECEx certified space heaters come with different wattage and optimised dimensions that offer cost-effective solutions to customers in varying industries.
