Volvo Explosion Protection Engine Kits (ATEX)

The Volvo Pyroban kits were developed to give an alternative to the popular 2 cycle DDC engines and they proved to be reliable and well matched to the hardy Volvo engine.  Whilst not actively developing further Volvo solutions we can continue to support the D5, D7 and D12 engines.  The systems are popular with fabric maintenance applications, cranes, and HPU’s  The D12 have been successfully utilised in Nitrogen Pumping and single pump skid applications.

Pyroban solutions are designed for reliable and efficient performance in harsh, offshore environments and eliminate the ignition risk. Certification to ATEX 2014/34/EU with all flame non-transmission testing (FNTT) has been completed at our UK facility in strict accordance with industry standards.
