Real-World Example
One of our clients — a European medical device startup — needed precision cooling inside a handheld diagnostic tool. Space was limited to just 200mm wide, and fan noise had to be near-silent.
We delivered a custom mini water chiller with a compact plate heat exchanger and a variable-speed DC compressor. The result: ±0.1°C stability, <30 dB noise, and 24/7 reliability — all inside a 2.5 kg unit.
This helped them pass EU thermal safety testing and launch their product 2 months ahead of schedule.

Frequently Asked Questions
How Does A Mini Water Chiller Work?
A mini water chiller removes heat by circulating cooled liquid (typically water or glycol mix) in a closed-loop cycle. The fluid absorbs heat from your device, returns to the chiller, and is cooled again using a mini rotary compressor.
✅ Perfect for space-limited systems that demand reliable, precise thermal control — such as electronics, batteries, and medical devices.
Where Are Mini Water Chillers Commonly Used?
They’re ideal for compact, high-performance applications, including:
-
Lithium-ion battery packs (e.g. drones, EVs)
-
Medical & lab equipment
-
Beverage/vending machines
-
Laser & semiconductor cooling
Customizable and compact — the go-to solution for OEMs building smart thermal systems.
What Is a Mini Rotary Compressor?
A mini rotary compressor is a small, DC-powered unit that drives the refrigeration cycle. It’s:
-
Quiet
-
Energy-efficient
-
Designed for tight integration in portable or embedded systems
It’s the core engine behind Lando’s ultra-compact chillers.
How Does It Cool a Lithium-Ion Battery?
Lando’s chillers use a plate-style liquid exchanger placed between Li-ion battery modules. Cold fluid circulates through the plate, absorbing heat evenly from both sides — keeping battery temperature stable during charge and discharge cycles.
Result: Longer runtime, better safety, no overheating — even under load.
