Name: COMET+ Cabinet Heaters
SKU: 25726
Availability: InStock

Product Description

The COMET+ range of gas and oil fired cabinet heaters are a cost-effective heating solution for many industrial large spaces. Available in a number of different sizes and variants, you can be sure to find the right solution for your needs. Standard efficiency models are available with modulating burner with a 2:1 turn down with use with Natural Gas (G20) and Propane (G31). These floor standing industrial and warehousing cabinet heaters are designed a sheet metal frame with galvanised powder
coated panels to form a rigid and durable casework. This industrial and warehouse cabinet heater is engineered for exceptional performance and long service life. At its core is an inversion combustion chamber combined with a four‑pass heat exchanger assembly, delivering enhanced thermal efficiency and improved heat transfer. This advanced design not only maximises output but also extends the operational lifespan of the unit.
The combustion chamber is manufactured from 304 stainless steel and paired with a high‑efficiency flat tube heat exchanger, achieving combustion efficiencies of up to 94% (NCV). To ensure durability and reliability, the complete heat exchanger assembly is mounted to accommodate thermal expansion, minimising stress and preventing premature component failure. For applications demanding even greater efficiency, the condensing version provides outstanding thermal performance, delivering significant fuel savings and reduced operating costs.

Model Range:

• Front flue connection (Rear connection as standard)

• External weather-proof casing models available

• Right-hand side (RHS) grill (Left-hand side (LHS) grill as standard

• Flat pack option available on request.

View the COMET+ cabinet heater Safari Park Case Study

Features and Benefits

• High efficiency condensing versions are available for all natural gas fired models
• The units may be specified for either free-blowing applications or use with ductwork
• Enhanced life expectancy as EC plug fan(s) circulate large air volumes evenly across the full heat exchanger surface
• Combustion efficiencies of up to 94%
• External weather-proof casing models available.

This advanced design not only maximises output but also extends the operational lifespan of the unit.
The combustion chamber is manufactured from 304 stainless steel and paired with a high‑efficiency flat tube heat exchanger, achieving combustion efficiencies of up to 94% (NCV). To ensure durability and reliability, the complete heat exchanger assembly is mounted to accommodate thermal expansion, minimising stress and preventing premature component failure. For applications demanding even greater efficiency, the condensing version provides outstanding thermal performance, delivering significant fuel savings and reduced operating costs.

Model Range:

• Front flue connection (Rear connection as standard)

• External weather-proof casing models available

• Right-hand side (RHS) grill (Left-hand side (LHS) grill as standard

• Flat pack option available on request.

View the COMET+ cabinet heater Safari Park Case Study

Features and Benefits

• High efficiency condensing versions are available for all natural gas fired models
• The units may be specified for either free-blowing applications or use with ductwork
• Enhanced life expectancy as EC plug fan(s) circulate large air volumes evenly across the full heat exchanger surface
• Combustion efficiencies of up to 94%
• External weather-proof casing models available.

Product Description

The COMET+ range of gas and oil fired cabinet heaters are a cost-effective heating solution for many industrial large spaces. Available in a number of different sizes and variants, you can be sure to find the right solution for your needs. Standard efficiency models are available with modulating burner with a 2:1 turn down with use with Natural Gas (G20) and Propane (G31). These floor standing industrial and warehousing cabinet heaters are designed a sheet metal frame with galvanised powder
coated panels to form a rigid and durable casework. This industrial and warehouse cabinet heater is engineered for exceptional performance and long service life. At its core is an inversion combustion chamber combined with a four‑pass heat exchanger assembly, delivering enhanced thermal efficiency and improved heat transfer. This advanced design not only maximises output but also extends the operational lifespan of the unit.
The combustion chamber is manufactured from 304 stainless steel and paired with a high‑efficiency flat tube heat exchanger, achieving combustion efficiencies of up to 94% (NCV). To ensure durability and reliability, the complete heat exchanger assembly is mounted to accommodate thermal expansion, minimising stress and preventing premature component failure. For applications demanding even greater efficiency, the condensing version provides outstanding thermal performance, delivering significant fuel savings and reduced operating costs.

Model Range:

• Front flue connection (Rear connection as standard)

• External weather-proof casing models available

• Right-hand side (RHS) grill (Left-hand side (LHS) grill as standard

• Flat pack option available on request.

The COMET+ range of gas and oil fired cabinet heaters are a cost-effective heating solution for many industrial large spaces. Available in a number of different sizes and variants, you can be sure to find the right solution for your needs. These floor standing industrial and warehousing cabinet heaters are designed a sheet metal frame with galvanised powder coated panels to form a rigid and durable casework. This industrial and warehouse cabinet heater is engineered for exceptional performance and long service life. At its core is an inversion combustion chamber combined with a four‑pass heat exchanger assembly, delivering enhanced thermal efficiency and improved heat transfer. This advanced design not only maximises output but also extends the operational lifespan of the unit. High‑efficiency condensing versions are available for all natural gas‑fired models, delivering up to 101% efficiency and providing significant fuel savings and reduced operating costs. These condensing cabinet heaters are ideal for facilities seeking to reduce energy consumption while maximising heat output. To ensure durability and reliability, the complete heat exchanger assembly is mounted to accommodate thermal expansion, minimising stress and preventing premature component failure.

Model Range:

• Front flue connection (Rear connection as standard)

• External weather-proof casing models available

• Right-hand side (RHS) grill (Left-hand side (LHS) grill as standard

• Flat pack option available on request.
