We supply box type condensing units for cold room wholesalers, installers, contractors, and end users.
Our range covers L / U / H / V Types for different installation spaces, cooling loads, and project needs.
Box type condensing unit is a compact refrigeration unit that combines the compressor, condenser, fan motors, receiver, and basic protection components inside one cabinet. This design keeps the unit clean, compact, and easier to handle for cold room projects.
Compare with open type condensing units (semi-hermetic type), a box type design gives better component protection and a cleaner layout for transport, installation, and site management.
Compare with monoblock units, it gives buyers more flexibility in evaporator matching and project configuration.
This type of unit fits many cold room applications, especially when buyers need standard products, easier handling, and stable batch supply for export and project use.
It works well for distributors, installers, contractors, and end users who want practical selection and easier field coordination.
Good fit for
Small and medium cold rooms
Distributed refrigeration projects
Export distribution orders
Standard project supply
Projects that need easy installation and clean equipment layout
Not the best fit for
Very large centralized cold room projects
Projects with very long piping runs
Sites with poor ventilation and very high ambient heat
Applications with strict noise limits and difficult airflow conditions
The table below shows common configuration ranges for selection.
Final data depends on room temperature, ambient temperature, refrigerant, compressor brand, and target market requirements.

Different cabinet structures do more than change the shape of the unit.
They affect airflow direction, service access, heat rejection, east layout, and site matching.
Buyers should choose the structure first, then confirm compressor, refrigerant, and working condition.
L Type units use a side-oriented layout that fits projects with limited installation space but still keeps practical service access. This structure works well for standard cold room and helps buyers handle batch purchasing and model selection more easily.

Many buyers choose by horsepower first. That often creates selection mistakes.
A better method starts with working condition, installation space, ambient temperature, and service access.
Choose by installation space:
If the machine area stays tight, choose a structure that uses cabinet space well and still leaves room for airflow and service access.
Choose by ambient temperature:
If the project runs in hot climates, check condenser capacity, airflow design, and high ambient configuration before you confirm the unit.
Choose by maintenance access:
If the site needs regular service and long operating hours, choose a structure that gives easier access to key components.
Choose by room temperature and cooling load:
Medium temperature and low temperature cold rooms need different compressor and refrigerant matching.
Don’t rely only on nominal HP.
Choose by project target:
Some buyers focus on first cost. Others focus on stability, easier maintenance, or repeat order consistency.
Your structure and configuration should match that target.
Quick inquiry prompt
If you send your project data, we can recommend the right type faster and reduce model mismatch.
Buyers usually contact us for one of these reasons:
They need model matching for a new project
They need a high ambient or custom power supply version
They need OEM support
They need condensing units with matching evaporators or refrigeration components
They need practical communication, not only a basic price list
We aim to support project fit, not only product supply.
You only need to send us your cold room size, room temperature, ambient temperature, and installation space. We will recommend the right type based on your project instead of asking you to guess by appearance.
Start with room size, target room temperature, ambient temperature, installation space, and power supply. Don’t choose by horsepower only, because final selection should match real working conditions and cooling load.
Not always. Medium temperature and low temperature rooms often need different compressor matching, refrigerant selection, and condition-based capacity checks, so buyers should confirm the exact room temperature before model selection.
Yes. We support different voltage, phase, and frequency options for different markets. Send us your local power standard, and we will check the right configuration for you.
Yes. Many buyers ask for a matched evaporator and related refrigeration components to simplify procurement and reduce selection errors. This approach helps installers and contractors save communication time and improve system matching.
Yes. We can support OEM nameplate, label, and packaging based on your order request. If you have brand requirements, send them with your inquiry.
Yes. We can offer high ambient versions for hot regions (ambient temp ＞+43°C). Please tell us the highest outdoor temperature, so we can match the right condenser and configuration.
Depend on the model. But common components include compressor, air cooled condenser, fan motors, receiver, filter, sight glass, and basic protection parts. We will confirm the full configuration before order.
Many box type condensing units support 220V, 380V, 415V, or 460V, with 50Hz or 60Hz options in 1 phase or 3 phase formats depending on model range. Buyers should confirm voltage, phase, and frequency before quotation because power mismatch can block installation and startup.
Check room temperature, ambient temperature, power supply, refrigerant, installation space, ventilation condition, and whether the project needs standard configuration or custom options. Buyers should also confirm what the standard unit includes, what optional parts are available, and whether the supplier supports technical documents, OEM, and after-sales communication.
