Product Description
Danfoss GD Heavy Duty fixed gas detection unit, code 148H6064, a factory-calibrated wall-mount detector for ammonia (R717) in refrigeration machinery rooms, cold stores and process plant. Electrochemical sensing element with a 0–100 ppm measuring range and two-level alarm relays (pre-alarm 25 ppm, main alarm 35 ppm). Relay outputs drive external alarm panels; no on-board display on this version. Operating temperature -40 to +50 °C. Supplied as a complete unit with mounting kit, cable gland and a factory calibration certificate. Supply 16–28 V DC. Integrates with Danfoss AK-SM system managers and standard alarm panels. HS 9027.10. OEM P/N 148H6064.

Compatibility & Fitment
Confirm the target gas (ammonia (R717)), detection range (0–100 ppm) and supply voltage (16–28 V DC) match the installation before ordering; the sensor element is gas-specific and factory-calibrated. Standard (non-ATEX) version — for classified hazardous areas order the ATEX/IECEx-certified Heavy Duty version instead.
