Master mod. BV 77 E

Master indirect diesel-fired hot air generator mod. BV 77 E.

Hot air generators are ideal for heating large spaces that are difficult to heat with traditional systems such as workshops, building sites, greenhouses, garages, livestock farms more.

This model is equipped with the smoke exhaust chimney: the smokes come out separately from the hot air produced through the exhaust pipe. Furthermore, the air outlet can channel the air flow.

This product is designed for professional use.

The manufacturer has recently updated the visual appearance, so the machines could feature two different colour customisations: either a black band (in the main photo), or the classic yellow colour scheme.

High-quality product Made in Italy.

How to select the ideal hot air generator according to your needs

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
