P-K MACH ‘n’ Roll Condensing Indirect Water Heaters

Models: MR300 (300 MBTU), MR399 (399 MBTU), MR500 (500 MBTU), MR750 (750 MBTU), MR1050 (1050 MBTU)


It’s a Matter of Size and Scale

The P-K MACH ‘n Roll is a highly efficient gas fired, condensing domestic hot water and heating system designed to produce reliable hot water delivery without scale build up.  This gives the MACH ‘n Roll the long term value and reliability you demand.


Big value in a tiny footprint

The P-K Mach ‘n’ Roll® system provides building heat and domestic hot water with little to no scale build up. It is ideally suited for commercial building applications such as schools, office buildings, apartments, hotels and offices. This efficient water to water heating system is manufactured from the highest quality materials combining a robust aluminum alloy heat exchanger above, with an indirect stainless steel heat exchanger below.  Both zones were individually engineered using different alloys that when used together, delivers higher efficiency and industry leading reliability.

Easier to maintain

Best of all, the P-K Mach ‘n’ Roll system was designed with service in mind. The indirect heat exchanger section is mounted on a pull out tray, making it fully accessible from the front of the boiler. Inspect, clean or repair the water side without having to “tear the boiler apart”. For full access, isolate the boiler and domestic lines, remove couplings and unions, take off the front access panel and slide out the heat exchanger.

Easier to install

The P-K MACH ‘n’ Roll system takes advantage of unused space underneath the boiler to create a package that delivers high-value in a smaller footprint than conventional fabricated systems. This lets you maneuver through a mechanical room door or onto an elevator, making installation easy anywhere, even in a penthouse or on the roof, without the need for expensive rigging or construction. The P-K MACH ‘n Roll system needs only five connections to get it running. Each unit is delivered with the boiler loop ready to go, and only requires connections to:

  • Domestic Water Supply
  • Return to Storage Tank
  • Electrical connection
  • Gas
  • Venting:
    • Polypropylene
    • Stainless Steel
    • CPVC

Features

  • Entire package fits in the boiler footprint
  • Domestic water loop is isolated from the boiler loop
  • Precise temperature regulation with no mixing valve required
  • Domestic Water Supply
  • Return to Storage Tank
  • Electrical connection
  • All the features of a P-K MACH® condensing boiler, including:
    • NURO® Control
    • Certified low NOx performance
    • Aluminum alloy heat exchanger
    • Full modulation burner with 5:1 turndown

Advantages:

  • Less prone to scale build up
  • Produce domestic water up to 140°F and still operate the boiler in the condensing mode, where peak efficiency performance can be achieved.
  • Designed with serviceability in mind, the indirect heat exchanger is fully accessible from the front of the boiler through the use of a pull-out tray mechanism.
  • Save space in your mechanical room.
  • Ideal for retrofitting old buildings.
