Mastry Helps OEMs Achieve EPA Compliance

August 4, 2014

Tier 4 EPA regulations create unprecedented challenges for many OEMs, as they require extensive testing to ensure end products are compliant. Mastry Engine Center now offers design and performance analysis services for its OEM customers to help with this hurdle. The diesel engine specialist said it can also streamline business for those who use its engine brands for their own equipment, with its sub-assembly and private label options.

Mastry draws from more than 50 years of industrial and marine diesel engine experience to help its customers succeed. It provides 3D modeling services in addition to EPA testing, to help ensure an OEM’s final product meets current regulations.

Mastry can supply custom frames, enclosures, harnesses, electronics and control panels for its diesel engine packages. Its sub-assembly work and private-label options give customers more flexibility and customization possibilities, up to Mastry supplying a complete end product. The company's in-house mechanical engineer has a background in equipment repair and assembly, and understands customers' unique product needs.

One company already benefitting from Mastry's services is Cavidyne LLC of Gainesville, Florida. This longtime customer first used Yanmar engines to power its ultra-cavitation underwater cleaning systems, many of which are still in use after years of service. For its new Concrete Blaster model, Cavidyne turned to Mastry for guidance on a higher-horsepower diesel that could transition from Tier 4i to Tier 4 Final in the same footprint, while minimizing size and weight.

Mastry helped design three Concrete Blaster models for Cavidyne using JCB 4-cylinder engines in 125 hp, 161 hp and 173 hp configurations. These diesels offer an excellent power-to-weight ratio in a compact footprint; many are smaller and lighter than 6-cylinder competitive engines. They are also available for qualified OEM applications without the unnecessary aftermarket diesel particulate filtration or selective catalytic reduction components.

To help Cavidyne streamline its product supply, Mastry will build and assemble the Concrete Blaster's frame and enclosure, and assemble the engine's electronics, control panel and wiring harnesses. "Mastry has vast engine experience," said Cavidyne president Dr. Ilia Kondratiev. "They're the best for service, delivery timeframe and honesty with the customer."
