SLTNS Engineered Systems® is a manufacturers' representative for the code-critical building systems that keep projects compliant and occupants safe — chimneys, special gas vents, commercial kitchen grease ducts, generator and engine exhaust, multistory residential exhaust, smoke control, combustion and make-up air, refrigerant leak mitigation, and more.

We support engineering firms and mechanical contractors from four offices: metro NYC/NJ, the DMV, South Florida, and Nashville.

𝘕𝘰 𝘱𝘳𝘰𝘣𝘭𝘦𝘮𝘴; 𝘰𝘯𝘭𝘺 𝘚𝘓𝘛𝘕𝘚®. Independently owned and operated, we've built our reputation on three principles:

𝗖𝗼𝗺𝗽𝗹𝗶𝗮𝗻𝗰𝗲. Our design team serves on the committees that write the codes — ASHRAE TC6.10, NFPA 54, NFPA 211, UL 103, and UL 378 — with working knowledge of the IBC, IFGC, IMC, and NFPA 92. That insight keeps your projects on the right side of every AHJ.

𝗛𝗼𝗻𝗲𝘀𝘁𝘆. We recommend the right solution for your project, even when it falls outside our portfolio. Long-term trust beats a single sale, every time.

𝗞𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲. Our engineers bring 40+ years of design experience — no reliance on manufacturer software to size a system. Our estimators know every product line cold, so the numbers you bid with are the numbers you can build to.

Have a tough spec, an AHJ comment, or a set of plans that need a second set of eyes? Send them over — we'll weigh in.

We also deliver 𝗮𝗰𝗰𝗿𝗲𝗱𝗶𝘁𝗲𝗱 𝗰𝗼𝗻𝘁𝗶𝗻𝘂𝗶𝗻𝗴 𝗲𝗱𝘂𝗰𝗮𝘁𝗶𝗼𝗻 for engineering firms and mechanical contractors — earning PDH, CPC, or CEH credits (NY, NJ, MD, FL) while tackling the code-critical challenges you're actually facing. Our most-requested topics right now:
- A2L refrigerant line shafts: ventilation and enclosure requirements
- Stairway pressurization controls
- Generator and engine exhaust systems
- Commercial kitchen grease ducts
