FOOD AND BEVERAGE Pasteurization, in particular, requires products to be heated to very specific temperatures to eliminate certain harmful pathogens, without overheat- ing and impacting taste. An increasing number of small craft brewers, micro-pubs and micro-dis- tilleries are enjoying the low costs as- sociated with low-pressure steam heat, while achieving consistent batches and reducing waste. In addition, food and beverage industries can use their steam boilers to create hot water through a steam-to-water heat exchanger for cleaning and other sanitizing needs. LABORATORIES Labs on college campuses utilize a tremendous amount of exhaust air when conducting experiments and tests. To make up for the large amount of exhaust air, the laboratories bring in an equal amount of outside air, which can be extremely cold in the winter, and require a significant amount of heat to warm up to neutral conditions. When the air is below freezing point, other forms of heating the building — such as hot water coils — may be more susceptible to freezing and damage. Low-pressure steam, however, is much less vulnerable to this risk and provides large heat capacities. LUMBER KILNS Mills often house a variety of specialty hardwoods used for making furniture, or cedar planks used for cooking, that require drying in a kiln. Using a low- pressure steam boiler enables mills to perform this function safely and effectively for standardized results, increasing the quality of the wood. The manageability and consistency of low- pressure steam heat make it ideal for these and other growing industries. FACTORS TO CONSIDER When selecting a low-pressure steam boiler, buyers should take inventory of their business' needs and facility amenities before making a selection. Most low-pressure steam boiler sys- tems are highly configurable to match the unique needs of different applica- tions. Furthermore, many low-pressure boiler systems can be built into existing systems or designed for new installa- tions — ensuring consistency and effi- ciency for each individual application. Further underscoring versatility, low-pressure commercial steam boil- ers come in a variety of sizes and run on several different fuel sources. High- quality options can operate on natural gas, propane, oil or a dual fuel option, while ranging in size. When evaluating boiler options, determine what is required for optimal production first and then build a system to match to avoid unneces- sary costs. For businesses with limited demands, there are simple atmospheric burners available at low costs. For higher-demand operations, power burner models allow for greater capac- ity and flexibility. Businesses with complex heating requirements may opt for a multiple boiler control system to run larger operations more efficiently.
