One-Stop OEM & ODM Cold Room Solution Partner
Condensing units (also called”refrigeration unit” or “cold room outdoor unit”) are used for refrigeration of various equipments. Main components: compressor, condenser, expansion valve, fan motor, control board, pipeline system, etc.
Compressor is the core component in condensing unit, usually called “main engine”. Refrigerant changes from low pressure to high pressure, the continuous flow and transport are all accomplished by the work of compressor.

When you want to wholesale condensing unit,or act as a dealers.
# Firstly you should double think some questions: what is your selling market features? What is your selling channels? Who is your competitor? etc. they are very important for us before giving you the final solution.
#1 Application
If you want to cool a whole project for cold room, container (20ft/40ft), supermarket, the household split type air conditioners are not suitable. As their application areas are so different.
Application areas for condensing unit:
2hp 10~20㎡; 3hp 15~25㎡
4hp 20~40㎡; 5hp 30~55㎡
6hp 40~80㎡, etc.
(HP means Horse Power)
Due to working temperature ( high, medium, low) the application areas are different even the same HP.
So please give your drawings and all information, we will supply you the solution.
#2 Refrigerant
Different refrigerants have different prices, and most countries forbade R22 refrigerant (Not R22 compressor), so double check your market or government the related policy, don’t make big mistake.
For condensing unit or refrigeration unit, there are more refrigerants’ options, like R404, R448a, R134a, R449a, etc. Let’s know your option or project details.
#3 Inverter or Non-inverter
Most people are puzzled by two types cooling way: inverter or non-inverter. In one word: Inverter condensing unit is more energy-saving, more stable, more bigger cooling area, better for low and unstable voltage areas. Of course, price is higher.
#4 Pricing
According to different working temperature & room size, we will recommend the most suitable & competitive refrigeration products.
What’s more, different compressors ( Copeland / Bitzer / Sanyo / Panasonic / Highly ) have different prices.
For condensing unit or refrigeration unit, you can choose from 0.5~50hp or even more.
Inverter condensing unit is higher price than non-inverter condensing unit.
#5 Reputation
Before confirming the order, should first verify the authenticity of supplier, if possible please visit the factory before purchasing
the products. What’s more, can ask some sample to test then you will have a brief understanding about this company and their managenment.
#6 Set Temperature
Different stored goods have different temperature requsts, and the cooling power is also different.
For example, frozen foods such as ice cream requires -18°C, transport of chilled meat requires -5°C, and the required temperature for fresh fruits and vegetables is also different. Especially for the cold chain transportation of vaccines and medicines, which need special temperature ＜-35℃.
Therefore, need to select suitable condensing unit or refrigeration unit according to different temperature requests.
In addition, some goods also require the refrigeration unit to have a defrosting function during transportation.
#7 Hermetic Way
Cold room refrigeration compressors can be divided into two types: semi-hermetic and hermetic due to their structure.
1) Semi-hermetic refrigeration compressor:
Adapt a wider pressure range and cooling capacity. Thermal efficiency is higher, cooling effect is more stable, and the unit power consumption is less. But the price is much expensive.
2) Hermetic refrigeration compressor:
The compressor and motor are installed in a welded or brazed shell, and share a main shaft, which not only cancels the shaft sealing device (decrease the possibility of leaks), but also greatly reduces size and weight of the entire compressor. But its price is cheaper than the semi-hermetic type.
#1 Package
Brand new condensing unit should use hard and sturdy wooden (Fumigation Free) package, firmly fixed. No broken or damage.
#2 Casing
Normally use zinc plated iron sheet, which has anti-rust function. The more even plated, the more better function of anti-rust. Of course, you can use stainless steel (SS) material, neven corrosion, but price is much higher.
#3 Component Condition
All parts should be brand new, especially the compressor, some suppliers use 2nd-hand or refurbished compressor to cheat clients, whose quality is very unstable.
#4 Welding
Qualified products will have dwell time for pressure one week or more before delivery to prevent any refrigerant leakage. Bad welding will easily leak refrigerant, made big money loss for clients.
#5 Compressor Type
Less than 3hp usually use rotary compressor ( Copeland / Sanyo / Highly ), more than 3hp use scroll compressor ( hermetic condensing unit) or piston compressor ( semi-hermetic condensing unit). Inverter condensing unit 2hp ~ 9hp all use ROTARY compressor (Sanyo / Highly).
#6 Noise
Brand new evaporator & condensing unit shouldn’t have a big noise (more than 45 dBA) when runs in 30 minutes, otherwise the compressor or fan (motor) uses poor quality, this kind of evaporator or condensing unit is not qualified.
#7 Voltage and Frequency
Condensing unit less than 3hp uses 220V normally ,but we also supply 380V. More than 3hp usually adopt 380-440V. What’s more, you should confirm your frequency , 50Hz or 60Hz, the unit price is different and misuse will damage your compressor even the whole condensing unit.
Notice: We can customize your Voltage.
Frequently Asked Questions About Condensing Unit
Condensing unit is responsible for condensing refrigerant vapor into liquid form by releasing heat, allowing the refrigeration system to remove heat from the desired space, finally cool down the room.
Speedway is committed to quality across all aspects of our business – our people, processes and products. We call this ‘the SPEEDWAY standard’.
Condensing unit receives high-pressure, high-temperature refrigerant vapor from the compressor. Refrigerant flows through the condenser coil, where it releases heat to the surrounding air or water, causing it to condense into a liquid, finally cooling the space or medium.
We welcome any sample order before big quantity purchase, that means 1pc is acceptable. For mass order quantity is 10pcs each model.
The two main types of condensers used in condensing units are air-cooled condenser, which use fans to blow air over the condenser coil, and water-cooled condenser, which circulate water to remove heat from the refrigerant.
We have own factory to produce the main refrigeration products, but we also do trading for other related products because we have resource to supply good quality and service.
Sizing a condensing unit involves determining the cooling capacity required for the specific application. Factors such as the desired temperature, ambient conditions, and the type of refrigerant will determine the appropriate capacity.

Yes. But indoor condensing units require proper ventilation and additional considerations for air circulation and condensate drainage.
The lifetime depend on factors such as maintenance, usage, and environmental conditions. On average, a well-maintained condensing unit can last 12~15 years or more.
It’s important to follow appropriate safety measures such as disconnecting power before performing maintenance or repairs, wearing personal protective equipment (PPE), and following proper handling procedures for refrigerants to prevent injury or accidents.
