The history of Puls-air


Then the great idea

In 1978, Austrian engineer Georg Pletzer was awarded a contract to develop a propulsion system for unmanned military target missiles. The engine in question was a pulsating combustion engine. The engines had 105 kp thrust (1,050 newtons) and were tested in the high-speed wind tunnel at the University of Stuttgart-Veihingen up to speeds of around Mach 0.7 (854 km/h). What was striking about these engines was their completely smokeless combustion. It was also noticeable that these engines generated a lot of useless heat. It was almost logical that a heater was developed from this, with an efficiency of 97%. 

The idea for Puls-air is born. As a man of action, the engineer immediately gets to work.

Still active: Puls-air heater built in 1989 with over 15,000 operating hours.
Puls-air goes to the start

SINCE 1984

In 1984, Georg Pletzer delivers the first pulse-air hot-air heater. He causes a sensation with spectacular campaigns such as "Austria's fastest man". The business picks up speed.

Son Werner Pletzer is also gripped by pulse-air fever. As the owner of a car dealership with a workshop, he is very familiar with the advantages of the product. With his own company, he takes over production and sales for the German market. In the meantime, Puls-air is also sold in Switzerland, England and the Czech Republic. In the 3rd generation, the Austrian distribution is now managed by grandson Luca Pletzer. 

You can finally get your heating costs under control for as little as around €200 per month

You can either buy or lease your Puls-air workshop heater at a low price.
It has never been so easy to heat your workshop at a low price.*

*Without down payment, residual value 10% of acquisition value (AW) plus VAT, term 48 months, only for Germany. Leasing offer through our partner MMV Leasing GmbH, subject to credit checks, etc. There are no additional costs. The stated leasing rate is the net rate (plus 19% VAT for Germany). Before conclusion of the contract, MMV Leasing carries out a contract acceptance check. 2 Warranty extension and steering wheels cannot be leased and must be ordered separately if necessary. In this case, the freight costs will not be charged again.


Basically you can say:

Puls-air standard with very good insulation 600 m³.

Puls-air Plus up to max 1800 m³ with good insulation, with poor insulation 1000-1200 m³.

Very well insulated are halls or workshops built up to 5 years ago. This means insulating glazing, gas concrete walls or sandwich panels 100 mm or 120 mm.

Poorly insulated halls, for example, are just masonry buildings with poor roof.

Room temperature as desired. Based on empirical values, the room temperature of the workshop can be reduced by approx. 4 degrees, while maintaining the same comfort level for the employees, because the heat comes from below. Compared to ceiling fans from above, therefore energy is senselessly wasted.

Yes, because a room thermostat is built into the unit, which automatically turns the unit off and on to maintain the set temperature.

The external fuel oil tank is to be obtained from the local heating contractor. Requirements: Double walled, leak detection & fire protection valve.

No, the unit can be connected to an external fuel oil tank via 8mm copper pipe. Attention: No return - single line system. The tank can be up to 30 m away and the height difference must be max. 3.5 m.

The advantage of the canister is that the device is immediately ready for use.

Approx. 57 dBa, measured in a reference room. The actual noise sensation in a normally equipped workshop or hall is a pleasant light hum.

Judging loudness is often difficult.
  • 30 dB: Whispering, own breathing sound.
  • 35 dB: Leaf rustling.
  • 40 dB: In the living room with the window closed.
  • 45 dB: Residential area without road traffic.
  • 60 dB: Entertainment (single conversation)
  • 70 dB: Open plan office.
  • 85 dB: Average road traffic.
  • 95 dB: Heavy traffic.

Puls-air Standard: 1.5 l/h at the economy level and 1.9 l/h at the full power level

Puls-air Plus: 1.9 l/h at the economy level and 2.5 l/h at the full power level

Attention: Do not calculate on the complete day, because the device always switches itself on and off by the thermostat to maintain the temperature.

We always ask the counter question: How much do you need at the moment? - From this minus 50% and then you have the sum (All in approximate figures)

Yes, but this must be connected by us according to the circuit diagram, because the fan must run after.

App control is possible. Your local electrician should contact us in this regard!

Basically there are 2 models: Puls-air Standard (up to 600m³) and Puls-air Plus (with good insulation up to 1,800m³). For even larger premises, 2 or more units can be operated together. Thus, even larger halls and workshops can be heated efficiently and economically.

  1. Disconnect the supply and return lines (attached to the right of the oil filter) at the oil filter and hang them in a container of fuel oil.
  2. Switch on the device and wait until it starts.
  3. When the device has started, reattach the two wires.
  4. Loosen the supply line (attached to the left of the oil filter) at the oil filter and also switch on the unit.
  5. Reattach the supply line, the problem should be solved.
