BullMach BM-DDH 20 Diesel hot air generator

The BullMach BM-DDH 20 diesel hot air generator is a cost-effective solution for anyone who wants to heat an outdoor environment, and is also recommended for use in closed but well-ventilated spaces (carefully read the instruction manual).

Indeed, it is designed for temporary heating of buildings under construction or repair. One of its main features is the direct combustion, i.e. all the combustion products are expelled together with the hot air produced by the heater. For this reason, adequate ventilation must be ensured during its use.

This generator produces a high hot air flow thanks to its 20 kW thermal power and large 600 m3/h air flow rate.

These technical features make the BullMach BM-DDH 20 hot air generator a high-performing heater which guarantees great performance.

This portable heater is versatile and extremely easy to transport, thanks to the wheels and the convenient carrying handle. (Both wheels and handle are provided on standard equipment).

The full-level indicator on the machine allows to easily check the fuel level into the fuel tank.

It requires very easy and immediate maintenance, allowing you to heat different types of rooms quickly.

How to select the ideal hot air generator

Important features that the Operator has to consider in order to choose the ideal gas heater which best suits his requirements according to the room that has to be heated up:

  • Dimensions of the area that has to be heated up [V]
  • The ideal temperature [ΔT] that has to be reached
  • Room thermal insulation [K]

High thermal insulation: k = 1

Medium levels thermal insulation: k = 2

Low levels thermal insulation: k = 3

No thermal insulation: k = 4

Therefore, the heat requirements can be also calculated by using the following formula:

V x ΔT x K [kcal/h]

For example:

V = width 4 m width, 12 m length, 3 m height, room volume = 144 m³

ΔT = outdoor temperature -5ºC, room required temperature +18ºC, room temperature = 23ºC

K = 4 not-insulated room

The formula above mentioned brings to the following result: 144 x 23 x 4 = 13 248 kcal / h, which has to be compared with the data written on the machine serial no. plate, which highlights this heater functionality being able to produce larger volumes of instant heat compared to that one needed.

Converting to kW is easy, just multiply the result by 0.001163, so 13248 x 0.001163 = 15.4 KW
