Why 227 Enterprise

227 Enterprise understood the realm of competing demands, where multi-zone VRF systems had to juggle refrigerant flow across many zones while regulating changing loads, temperature swings and unceasing operational cycles. Traditional joints sacrificed something to achieve something else. 227 Enterprise explored a different question: What if refrigerant distribution could be perfect in every situation? The TA Series was the solution – precision developed to orchestrate perfect thermal homeostasis – delivering exactly what each zone needs, when it needs it. Compatible with R410A and R32 refrigerants, the TA Series is designed for challenging situations and built with exceptional durability. The TA Series doesn’t just move refrigerant, it makes invisible plumbing the foundation for operational excellence. The TA Series is 227 Enterprise’s promise to the demanding requirements of HVAC professionals worldwide, and to the rigorous expectations of large-scale commercial systems: unwavering reliability, uncompromising precision and performance that sets the standard for all others to follow.
