PSI’s 21.9-liter engine.

PSI recently extended its supply agreement with Doosan Infracore Co., Ltd. (“Doosan”), a leading global machinery manufacturer.

The new agreement extends PSI’s existing distribution rights for Doosan’s product line through 2023. PSI distributes Doosan’s 8.1 through 22-liter natural gas engines to OEMs serving power generation markets, commercial standby, demand response, oil and gas, and mission-critical applications.

“We are excited to continue our relationship and build on our continued success with our partnership with Doosan that secures our long term growth plans with industry-leading products,” CEO John Miller said.

In addition to the Doosan line, PSI offers 32-liter, 40-liter and 53-liter engines developed in conjunction with Weichai, its strategic partner.
