Col­lab­o­ra­tion Pow­er: BU Pow­er Sys­tems and ATMOS Chrást

The roots of the tra­di­tion­al Czech man­u­fac­tur­er ATMOS Chrást go back to 1899. As one of the world’s lead­ing com­pa­nies in the com­pressed-air sec­tor, ATMOS has around 50 years of expe­ri­ence in the con­struc­tion of mobile com­pres­sors. Mobile ATMOS com­pres­sors are par­tic­u­lar­ly robust and reli­able. They can be used under the most extreme con­di­tions. They can be used in the Siber­ian tun­dra, at tem­per­a­tures as low as ‑40° C, as well as in the cor­ro­sive envi­ron­ment of the coastal regions of South Amer­i­ca or in the extreme tem­per­a­tures of the Ara­bi­an Penin­su­la. ATMOS com­pres­sors are also used in the Sahara desert, as they have fil­ters and sep­a­ra­tors spe­cial­ly designed for dusty environments.

The PDP series com­pres­sors are equipped with a soft-start sys­tem that pro­tects the engine and the screw block. This means that the com­pres­sor idles after start-up, giv­ing it time to reach the cor­rect oper­at­ing para­me­ters. All PDP Series com­pres­sors are equipped with Perkins engines, which meet the high demands of oper­at­ing reli­ably even under extreme con­di­tions and, as one of the key com­po­nents, have a direct influ­ence on the reli­a­bil­i­ty of the machine.

The new ATMOS PDP 50 portable diesel screw com­pres­sor promis­es extreme ver­sa­til­i­ty. It can be sup­plied with pres­sures of 7, 10, 12 and 14 bar. It is the ide­al machine for sand, soda and dry ice blast­ing, air tools, pile dri­vers, drilling or push­ing out fibre optic cables for telecom­mu­ni­ca­tion projects.

The new ATMOS PDP 50 ben­e­fits from a fuel-effi­cient Perkins engine with diesel par­tic­u­late fil­ter. The engine com­plies with Stage V and is thus cer­ti­fied for envi­ron­men­tal zones where less mod­ern machines are not allowed and are even exclud­ed from pub­lic ten­ders. The 3‑cylinder mod­el is one of Perkins small­est engines, com­bin­ing per­for­mance, low oper­at­ing costs and an ultra-com­pact package.

To pro­tect the machine, elec­tron­ic con­trols have been fit­ted to mon­i­tor all impor­tant para­me­ters. The new PDP 50 has large, sep­a­rate air fil­ters for the engine and fan to ensure long main­te­nance inter­vals. The large diesel tank allows oper­a­tion for more than 8 hours with­out refill­ing. As a Perkins 400 Series engine, the Perkins® 403J-E17T is high­ly com­pet­i­tive in terms of per­for­mance and fuel econ­o­my. Through appro­pri­ate use of tech­nol­o­gy, these engines have been designed to be reli­able and to offer low cost of own­er­ship in the wide vari­ety of mar­kets they serve.

The PDP 50 can be equipped with a vari­ety of options to opti­mise the com­pres­sor for near­ly every indi­vid­ual appli­ca­tion. There are many options for com­pressed air treat­ment, e.g. dry air (after­cool­er with con­den­sate drain and heat exchang­er). The com­pres­sor can also be cus­tomised for use in haz­ardous areas such as refiner­ies (spark arrestor, Chal­wyn valve) or in nature reserves (with bot­tom tray as stan­dard to pro­tect against leakage).

“Our PDP series com­pres­sors ben­e­fit from an excep­tion­al­ly long ser­vice life, not least due to the sol­id engines. In addi­tion, with Perkins we can rely on an estab­lished and glob­al ser­vice net­work. This is very impor­tant for us as a lead­ing glob­al sup­pli­er,” says Franz Weis­brod, Inter­na­tion­al Sales Direc­tor at ATMOS Chrást “In addi­tion, the ATMOS PDP series com­pres­sors can be flex­i­bly con­fig­ured. Depend­ing on the loca­tion and the cus­tomer’s require­ments, there are a wide vari­ety of options. With the Perkins 400 series motor, we have cho­sen a motor that can respond flex­i­bly to these wish­es and that runs robust­ly and reliably.”
