STORM_front CORRECT DECALThe P-K STORM™, Patterson-Kelley’s newest contribution to the commercial boiler industry, has made its way to the market. The unit is designed to be efficient, cost-effective, durable and technologically superior than the competition. This 316L stainless-steel condensing boiler maximizes heating capacity during peak loads, while capitalizing on efficiencies.

The P-K STORM™ utilizes multiple channels in a helical coil orientation over an extended surface area. This feature allows for pressure drops as low as 4.3’ @ 40°F temperature differentials. This reduces the costs of operation and installation by requiring smaller pumps and applying less electrical energy. The efficiency of the P-K STORM™ also comes from its built-in 10:1 mechanical turndown. This means that the operating efficiency of the appliance at off-peak loads will exceed its rating of 97% thermal efficiency, putting the P-K STORM™ at the forefront of its class.

State-of-the-art cabinet and heat exchanger design offer unparalleled serviceability for maintenance, in addition to reduction in cost for installation and operation. Through Patterson-Kelley’s combustion intake design, entry into the heat exchanger happens in a matter of minutes, instead of a matter of hours. The heat exchanger door swivels open to provide full access to the heat exchanger tubes and burner inside the unit. In doing so, this makes routine maintenance on the appliance not only simple, but cost-effective.

The first wave of P-K STORM™ products are offered in four sizes: 1250, 1500, 1750 and 2000mbtu. Outdoor technology is available as an option on all models, allowing for greater flexibility in placement of the equipment. Every model comes standard with our NURO® Touch Screen Control System for seamless boiler operation. NURO® Connectivity provides seamless visibility to the boiler functions, available to monitor and adjust your facility system at the touch of a screen.
