Quality Control
Cold chamber test – Every unit runs at -30°C for 2 hours. Heater must hold internal temp above 0°C.
Hot chamber test – 55°C for 4 hours at full load. No over‑temp alarms.
IP56 water test – High‑pressure spray from all directions for 10 minutes. No water inside.
Sand test – Blown sand against the intake for 30 minutes. Filter catches it.
R&D Results
Heater placement – First unit had heater near the top. Heat rose, bottom stayed cold. Moved to the bottom. Much better.
Filter design – Original filter clogged fast in heavy dust. Switched to a cyclonic pre‑filter. Lasts 10x longer.
Door seals – Used automotive‑grade bulb seals. Stays flexible down to -40°C. No cracking.
Customer feedback – An Arctic operator wanted a way to check internal temp without opening the door. Added a display on the outside.
Packaging and Transportation
Shipped from Xi'an – On a heavy skid, bolted down, covered with a breathable waterproof cover.
No crate needed for domestic – The unit itself is the crate. For export, add a wooden crate.
Documentation – Laminated cold weather quick start, full manual on USB.
Extra filter – One spare filter included.
After‑Sales Service
1‑year warranty – Covers electronics, heater, fans. Filters are consumable.
Spare parts (heater element, fans, control board) kept in Xi'an.
Email support – We answer within one business day. Include temperature readings.
Qualification Certification
CE – LVD and EMC.
MIL‑STD‑810 – Environmental test report available.
ISO 9001:2015 – Our Xi'an facility.
FAQ
Q1: Do I need a separate power source for the heater?
A: No. The heater runs off the input power when the unit is plugged in. No extra connection.
Q2: Can I use this in a cold climate without the heater?
A: Not recommended. Electrolytic capacitors lose capacitance below -10°C. The heater keeps them warm. Without it, the unit may fail to start.
Q3: Is the filter washable?
A: The primary foam filter is washable. The secondary paper filter is not – replace it. We include one spare.
Q4: What's the difference between IP56 and IP54?
A: IP54 is dust‑protected and splashing water. IP56 is dust‑tight and high‑pressure water jets (hose down). This unit can be pressure‑washed from a distance.
Q5: Lead time from Xi'an?
A: 5‑6 weeks. The heater and sealed enclosure are built to order.
