SLTNS Engineered Systems® prides itself on exceeding your expectations. We believe in maintaining long-term relationships and not focusing on short-term gains. To preserve our relationships, we always apply three principles to each project: COMPLIANCE. Our engineers are active members of various code and standard committees including ASHRAE’s TC6.10, NPFA 54, NFPA 211, and UL 378. In addition, we have a thorough understanding of the IFGC, IMC, ANSI/UL 864 and NFPA 92. HONESTY. We believe in long-term customer relationships. In order to build loyalty and trust with our customers, we always provide you and your client with the proper solution even it does not fit within our product portfolio. KNOWLEDGE. Our engineers have over three decades of design experience so we don’t have to rely on computer programs or manufacturers to provide guidance on your design. Additionally, our estimators have full knowledge of our product line to ensure your questions get answered correctly.
