Chiller Temperature Sensor
A failed temperature sensor stops the chiller. A drifting one doesn’t, and that’s the expensive case. The machine keeps running, no alarm appears, and the controller acts on a plausible but wrong number with complete confidence. Compressors over-load or the plant under-cools, the energy bill climbs, and nobody connects the cost to a component the size of a pen.
Cool.sa supplies genuine OEM temperature sensors for chillers operating across Saudi Arabia, stocked inside the Kingdom rather than ordered from overseas. Every part is confirmed against your photos and unit details before you order, comes with a VAT invoice, and ships to project sites Kingdom-wide.
Send us a photo of your sensor and the unit nameplate on WhatsApp and we’ll identify it.
Which Sensor Do You Need?
| Comparison | Water temperature | Discharge protection | Standard temperature |
| Function | Measures entering / leaving water | Trips on high discharge temperature | General measurement across the machine |
| Class | Measurement | Protection | Measurement |
| Programming | Not usually required | Not required | Often required |
| Typical symptom | Drift, implausible delta T, rising energy use | Compressor won't start; protection alarm | Frozen reading, sensor fault message |
Why Genuine Matters More on Sensors Than Almost Anything Else
Copies of common sensor part numbers are widely available at very low prices from overseas platforms. The problem is that a copy works, it produces a reading, the controller accepts it, nothing alarms.
But if the thermal curve differs slightly from specification, the controller is reading a wrong number and believes it. On a protection thermistor, the equivalent problem is worse: a trip point that's ten degrees high means a cheap part is nominally protecting an expensive compressor while not actually protecting it. You find out the day the compressor fails.
Brands We Supply
Genuine OEM sensors for York, Trane, Hanbell, Carrier and other chiller and compressor platforms operating in the Kingdom. Hanbell compressors in particular are fitted inside chillers assembled under many brands what matters is the compressor nameplate, not the name on the chiller casing.

Frequently Asked Questions
Q1. How do I tell a drifting sensor from a failed one?
A failed sensor typically gives a frozen or out-of-range reading. A drifting sensor gives a plausible but incorrect reading, which is why it can go undetected. Comparing the sensor against a reference instrument is the most reliable way to identify sensor drift.
Q2. Does a new chiller temperature sensor need programming?
It depends on the manufacturer. Some sensors are supplied unprogrammed and must be configured to the unit using a service tool. An unconfigured sensor can appear exactly like a faulty one, so ask us before ordering to confirm the requirements.
Q3. Do I need heat conductive compound?
Yes, for any sensor installed in a thermowell. A dry well can cause the sensor to respond slowly and read lower than the actual temperature, which is a common reason a correctly functioning new sensor is mistakenly considered defective.
Q4. My sensor's part number doesn't match anything current. Is it superseded?
Very likely. Send us the existing part number and we'll confirm the current replacement. We'll also check whether the connector generation means you need a harness adapter.
Q5. How many sensors do I need?
A chiller measures temperature at several points, and manufacturer sensor kits often contain multiple identical units. Send us your chiller model and we'll confirm the required quantity before you order.
