Master BLP 73M – Direct Gas Heater

HOME » » Climate » Temperature Control » Heating » Direct Gas Heaters » Master BLP 73M – Direct Gas Heater

The BLP M range are direct gas fired air heaters, with manual ignition.

Master gas heaters provide large volumes of instant heat. They are very cost-effective, robust and efficient. Portable gas heaters are best suited for well-ventilated areas, which is a consideration for some highly-controlled grow-environments.

Master heaters are plug and play: they do not need installation. They are portable, can warm up very quickly, and can be controlled by a remote thermostat. Master heaters are designed to minimise environmental impact, they are robust and designed to last many years. Spare parts are also available for at least 10 years, increasing life expectancy. Master offers a 3-year warranty on all products for peace of mind.
