Once again, Harsco Industrial Patterson-Kelley leads the industry into a whole new dimension with a boiler of vastly greater capability and performance precisely tailored to today’s conditions and requirements: the P-K MACH® boiler.

Research shows the P-K MACH® boiler features the best, most advanced metallurgy ever offered in a commercial heating boiler. The P-K MACH® boiler works as well in older systems as in modern ones and in a wide range of temperatures to achieve unprecedented cost savings and efficiencies. After installing the P-K MACH boiler®, countless users have been able to reduce their fuel bills as much as 80 percent.

All P-K MACH® boilers, including dual fuel boilers and outdoor boilers, come standard with our easy to operate ENVI® control system. The ENVI® control even allows a P-K MACH® boiler to be paired with a P-K MODU-FIRE® FD boiler to create a cost-effective hybrid boiler system.

The P-K MODU-FIRE® Forced Draft boiler is a full modulation design that changes both fuel and air at a constant ratio to match boiler output to actual heat demand. With a constant fuel to air ratio and smooth 5:1 turndown that can track varying loads down to 20% of rated capacity, efficient and clean combustion can be achieved across the entire firing range of the boiler.

All P-K MODU-FIRE® Forced Draft boilers now come standard with Harsco Industrial Patterson-Kelley’s ENVI® control system. Advanced features such as cascade sequencing and building management system integration via MODBUS® protocol makes it easy to set up and manage P-K MODU-FIRE® Forced Draft boilers, even when used in a hybrid system design with P-K MACH® condensing boilers.

Show DetailsP-K ENVI® Control

Designed to maximize efficiency, the P-K ENVI® control system monitors and modulates the combustion and ignition of the boiler to maintain the desired outlet temperature. This flexible boiler control system can run a single boiler or a master/member network of up to 16 boilers. The lead/lag setup and boiler start rotation ensures run times are equally distributed across each unit in the system, extending the life of the boilers.

P-K ENVI® control is an on-board control system, eliminating the need for external control panels and reducing ancillary component costs. Control both condensing and non-condensing boilers in a hybrid system for maximum efficiency at minimum cost.

P-K ENVI® control system is now available on all P-K MACH® condensing boilers and P-K MODU-FIRE® forced draft (FD) boilers.
