RTU Economizers are becoming an increasingly popular innovative concept in technology, and they deserve a better definition than the typical business jargon. In simple terms, an RTU Economizer is a device that reduces energy costs by taking advantage of naturally occurring cooling effects due to outdoor air temperatures. It does this by pre-cooling outdoor air before it enters an air conditioning system, creating a more efficient working environment for your HVAC systems. As RTU Economizers become more popular and widely used in commercial buildings of all sizes, understanding their benefits and how they can save your business money should be paramount in any business plan.
