Applications, Advantages & Highlights of KN Boilers

Modern boiler applications call for technology that is innovative, flexible and adaptable. KN Series cast iron boilers were purposefully engineered to live up to today’s toughest applications and challenges, providing versatility in boiler system configuration and installation without sacrificing the bottom line.

In this day and age, the word ‘hybrid’ gets thrown around often. But what about the terms ‘base load’ or ‘mixed-boiler? Within the commercial boiler market, the concept behind these configurations is simple, lower the upfront equipment cost of a complete condensing boiler plant by incorporating new units into an existing and less expensive non-condensing boiler plant.

With a hybrid boiler system that combines KN Series condensing boilers within an existing, non-condensing boiler plant, operators are able to meet total BTU requirements while optimizing overall system performance, increasing boiler efficiency under various climate, seasonal and load conditions. By operating during most of the heating season, the condensing KN Series units provide the bulk of the high-efficiency BTU output when loop temperatures are low, while the existing and less-efficient non-condensing units act as supplemental boilers when outdoor temperatures fall and boiler loop temperatures increase.

Aeroseal and its unique benefits

Aeroseal is a proven, patented technology that seals the duct from the inside out.Virtually every duct system has a substantial amount of duct leakage which has been accepted as a necessary evil in our industry. On average, commercial duct systems lose between 25-40% of heating & cooling energy through the duct work.

Features & Benefits of Aeroseal:

  • Reduces duct leakage by 90-95% – typical duct leakage rates are redces from 20-30%, down to 2-3%
  • Seals up to a 5/8” hole – seeks out and finds virtually every existing crack, hole or seam without removing existing duct wrap
  • Seals up to 10” of duct static
  • Saves Fan HP - A 15% leakage rate equates to a 40% increase is system fan HP
  • VERIFIABLE – as the duct is sealed, the system documents the initial leakage rate, the reduction in leakage and the final system leakage rate and graphs the sealing process in the final report
  • SYSTEM BALANCE – Supply, return and/or exhaust air is delivered to the spaces it was designed for. Reduces the practice of increasing sheaves and fan BHP to overcome system shortcomings
  • Durable – Aeroseal is warranted on commercial jobs for 3 years and has a life expectancy of 40+ years
  • Safe – Aeroseal emits no known carcinogens or toxic substances (MSDS attached)
  • Payback – Typical paybacks are between 2-7 years

Geothermal HVAC Systems & their Benefits

Carrier and Bryant recently launched new geothermal product lines. Geothermal HVAC systems have been used for over 60 years in the US and other Western countries, and their use is growing exponentially. While geothermal systems are more expensive to install than ordinary systems, they offer two key advantages. First, they offer significant long-term cost savings. The US Department of Energy has found that they can save the average home hundreds of dollars in utility costs while the system pays for itself in 8 to 12 years. Second, a geothermal HVAC system can be designed to handle multiple needs simultaneously. For example, this kind of system can work to heat water, a pool, and a house all at the same time.   Continue reading
