Energy-Saving DC Compressor
Variable speed DC compressor with R134a/R513A. Up to 35% lower power consumption than AC units. Contributes to longer battery life in off-grid sites.
Tool-less filter maintenance
Easily cleanable, reusable metal mesh filter. Reduces downtime. Side-mount, roof-mount, and embedded versions for any cabinet type.
UL / CE / CCC / IECEx
Full global certifications: UL 60335 (recognized), CE, UKCA, SAA. Also ATEX for explosive atmosphere cabinet cooling (optional).
Custom-engineered DC solutions
Our in-house engineers adapt voltage, capacity, mounting, and communication to your exact project. Flexible ODM/OEM for panel builders.
Renewable energy & off-grid ready
Specifically engineered for photovoltaic combiner boxes, wind turbine control cabinets, and battery energy storage systems (BESS). Our DC air conditioners operate directly from 48V battery banks, reducing conversion steps. With ultra-low inrush current, soft start, and wide voltage tolerance, they ensure stable cooling even when batteries fluctuate. RS485 allows remote monitoring of power consumption.
Side-mount & Embedded DC units
Our DC cabinet air conditioners fit standard 19” racks and cabinet cutouts. Side-mount versions (flush or protruding) save interior space; embedded versions allow door mounting without compromising seal. All include closed-loop cooling to keep electronics free from humidity and dust. Ideal for telecom cabinets, charging stations, and outdoor enclosures. Temperatures set via digital controller.

What DC voltages are available?
We offer 12V, 24V, 48V, 72V, 110V DC standard models. For railway or special projects, we can customize input ranges 24V-110V wide input with internal regulation. All include under-voltage/over-voltage protection.
How to calculate required cooling capacity?
Based on cabinet internal heat load (W) and ambient max temperature. Our technical team provides free calculation sheet. Typically, choose unit with cooling capacity 20% higher than heat dissipation. 500W to 5000W covers most.
Can these run on solar without battery?
Yes, if you have stable DC bus. However we recommend a small buffer battery for compressor startup. Many clients pair with 48V lithium bank. We offer integrated charge controller option.
Are they compatible with ABB/Schneider cabinets?
We collaborate with major panel builders. Our units fit standard cutouts and include mounting brackets for third-party cabinets. UL/CE certified for safety.
What maintenance do they require?
Very low: clean or replace external filter every 3-6 months depending on dust. Sealed DC compressor needs no oil change. Self-diagnostic LED alerts for service.
Do you provide sample for testing?
Yes, we offer evaluation samples with fast shipping. Nominal fee covers shipping, deductible for first order. 24/7 tech support for integration.
