Sentech product offering
Product offeringCore offering
SenTech Corporation designs, manufactures, and sells infrared-based 'Early Warning' refrigerant gas leak monitors and fire suppression agent leak detectors used by HVAC&R, commercial refrigeration, data center, and industrial customers. The product line includes single-zone units, multi-zone units supporting up to 16 detection points from a single enclosure, and dedicated fire suppression agent (Halon/FM-200) monitors, all engineered to comply with ASHRAE Standard 15. Sales are conducted factory-direct and through authorized distributors, with technical support and factory repair services as ancillary offerings.
Product overview
SenTech Corporation manufactures infrared-based refrigerant loss monitoring systems and fire suppression agent leak detectors. The product portfolio consists of three core product lines: the IR-SNIF 1,2,3 Single Zone Monitor for small applications, the IR-SNIF-MCD Multiple Zone Monitor available in 1, 2, 4, 8, and 16 zone configurations for broader coverage, and the SSG-MCD Fire Suppression Agent Monitor also in multi-zone configurations. These systems utilize advanced NDIR (Non-dispersive infrared) and pyro-electric technology to detect refrigerants and fire suppression agents at concentrations as low as 1 PPM. The monitors support various accessories including 4-20mA analog outputs for building management system integration, individual zone relay options for multi-area notification, NEMA 4 enclosure upgrades for harsh environments, and audible/visual alarm devices. The products comply with ASHRAE Standard 15 safety requirements and are ETL listed to UL and CSA standards.

Sentech competitors and assessment
Company assessmentBroad incumbents
- Honeywell Analytics: Honeywell is both a Sentech customer (building controls) and a broad industrial gas detection incumbent. Its fixed and portable gas detectors compete with Sentech in HVAC, data center, and refrigerant leak monitoring, bundled with broader BMS offerings.
- Industrial Scientific: Industrial Scientific provides fixed and portable gas detectors used in industrial and commercial facilities, including refrigerant leak detection. Their offerings compete in process cooling, data center, and large chiller applications similar to Sentech's MCD multi-zone systems.
- Dräger: Dräger is a global industrial safety and gas detection company offering fixed gas detection systems for refrigerant and toxic gases used in commercial refrigeration, data centers, and industrial facilities — overlapping Sentech's chiller room and process cooling use cases.
- MSA Safety: MSA Safety is a large diversified safety equipment manufacturer with fixed gas detection systems used in chiller rooms, refrigeration plants, and industrial process cooling — directly comparable to Sentech's multi-zone refrigerant monitoring applications.
Regional players
- Riken Keiki: Riken Keiki is a Japanese manufacturer of fixed and portable gas detectors including refrigerant leak detection, primarily serving APAC. Comparable technology and use cases to Sentech but with limited overlap in the North American market.
Direct peers
- Bacharach: Bacharach is a direct competitor in commercial refrigerant and combustion gas leak detection, offering portable and fixed monitors used by HVAC technicians and facility operators — directly overlapping Sentech's IR-SNIF product line and customer base.
- Amprobe (Fluke): Amprobe, part of Fluke, produces refrigerant leak detectors and HVAC diagnostic tools. Their detector line targets the same HVAC technician and contractor channel that buys Sentech's single-zone monitors for chiller and refrigeration service work.
- Testo: Testo manufactures refrigerant leak detectors and HVAC measurement instruments used by contractors and facility operators. Their portable and fixed refrigerant monitors directly compete with Sentech's IR-SNIF series for the same ASHRAE-15 compliance applications.
Emerging players
- Crowcon Detection Instruments (Halma): Crowcon, a Halma subsidiary, manufactures fixed gas detection systems including refrigerant monitors used in commercial refrigeration and HVAC facilities. Their product line overlaps with Sentech's chiller room and supermarket applications.
- TPI Corporation: TPI Corporation supplies HVAC test instruments and refrigerant leak detectors aimed at the contractor and HVAC service channel. Their handheld and fixed detectors compete in adjacent price points to Sentech's single-zone IR-SNIF for smaller chiller applications.
