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 and pipeline, etc.
Compressor is the most important equipment in the condensing unit, usually called “main engine”. Refrigerant changes from low pressure to high pressure and the continuous flow and transportation are all accomplished by the work of the compressor.
Speedway is a condensing unit manufacturer in China, produce both inverter and non-inverter condensing unit.

No worry, our cooling capacity tonnage calculator will help you !
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.
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 10~20m2; 3hp 15~25m2
4hp 20~40m2; 5hp 30~55m2
6hp 40~80m2, 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.
Different refrigerants have different prices, also most countries are forbidden 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-voltage areas. Of course, price is higher.
According to different working temperature & room size, we will recommend the most suitable & competitive refrigeration products.
What’s more, different compressors ( Copeland / Sanyo / Panasonic / Highly ) have different prices.
For condensing unit or refrigeration unit, you can choose from 0.75hp up to 50hp or even more.
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 for some sample for testing then you will have a brief understanding about this company and their managenment.
#6 Required Temperature
Different stored goods have different temperature requirements, and the cooling power is also different.
For example, the delivery of frozen food such as ice cream generally requires a low temperature of -18°C, transportation 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 requirements of temperature.
Therefore, need selecting the suitable condensing unit or refrigeration unit according to the different temperature requirements.
In addition, some goods also require the refrigeration unit to have a defrosting function during transportation.
#7 Hermetic Way
Cold storage refrigeration compressors can be divided into two categories: semi-hermetic and hermetic due to their structure.
1) Semi-hermetic refrigeration compressor:
It can adapt to a wider pressure range and cooling capacity requirements. Thermal efficiency is higher, cooling effect is more stable, and the unit power consumption is less. But the price is much expensive.
2) Hermetic sealed 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.
Brand new condensing unit should use hard and sturdy wooden (Fumigation Free) package, firmly fixed. No broken or damage.
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.
#3 Parts Condition
All parts should be brand new, especially the compressor, some suppliers use second-hand or refurbished compressor to cheat clients, whose quality is very unstable.
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, bringing 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).
Brand new evaporator & condensing unit shouldn’t have a big noise (more than 45DB) 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.
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’.
The condensing unit receives high-pressure, high-temperature refrigerant vapor from the compressor. The 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 condensers, which use fans to blow air over the condenser coil, and water-cooled condensers, 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.

While condensing units are typically installed outdoors, there are indoor installation options available. Indoor condensing units require proper ventilation and may require additional considerations for air circulation and condensate drainage.
The lifespan of a condensing unit can vary depending on factors such as maintenance, usage, and environmental conditions. On average, a well-maintained condensing unit can last 12~15 years or more.
When working with a condensing unit, 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.
