Buyer's Guide

Four Questions Worth Asking Before You Choose a Supplier

These aren't sales points -- they're the things that actually determine whether your cold room earns money or costs you more than expected.

Capacity Sizing

Is the Capacity Actually Right for Your Room?

An undersized refrigeration unit never reaches temperature and spoils your product. An oversized one wastes energy every single day for years. Getting the capacity calculation right -- based on your room volume, product load, ambient temperature, and door-opening frequency -- matters more than the price on the quote.

Long-Term Cost

What Will This Cold Room Cost You After You Buy It?

Panel insulation quality and joint sealing don't show up on a spec sheet, but they show up on your electricity bill for the next 10-15 years. A cheaper panel with poor sealing can quietly cost far more in energy loss than the money it saved upfront.

Installation Risk

Who Actually Installs It -- and Do They Know What They're Doing?

Incorrect panel jointing, poor sealing at floor level, or wrong pipe sizing during installation can cause frost bridges, condensation, and leaks that aren't visible until months later. Clear installation guidance from people who understand the equipment matters as much as the equipment itself.

After-Sales Support

If a Part Fails Next Year, How Long Until You're Running Again?

A cold room only earns money when it's running. If a compressor or control board fails and spare parts or technical support are hard to reach from overseas, every day of downtime is lost product and lost revenue. Knowing your spare parts and support plan before you buy is as important as the purchase itself.
