Easy to install and service/Natural gas R290/Embraco compressor/EC fan motor

A top mount refrigeration unit is a all in one refrigeration unit installed for top mounting of the commercial chiller fridge and freezer. It is a kind of packaged refrigeration unit with hermetic compressor, condenser, condenser fan motor, filter drier, capillary, evaporator, evaporator fan motor, accumulator and other refrigeration components. These components combined into  plug and play refrigeration units, with the benefits of easy installation and highest quality construction standards, which are easy for customers to use. Top mount monoblock refrigeration unit widely used in upright refrigerators, upright freezers, beverage coolers, and commercial display cabinets. According to different cabinet temperature, it has monoblock cooling unit fpr upright refrigerator and monoblock freezing unit for upright freezer.

What is a Top Mount Monoblock Refrigeration Unit?

Top mount refrigeration unit is a integrated refrigeration system, unlike the traditional split refrigeration systems which the condensing unit is separate from the evaporator, refrigerant piping and on-site charging. The top mount refrigeration unit arrives factory assembled and tested, significantly reducing installation time and maintenance requirements.

Top mount monoblock refrigeration unit is a kind of monoblock refrigeration unit, designed for top-mounted installation for commercial refrigerator, upright freezer, display refrigerator, or refrigerated cabinet, so also called roof mounted refrigeration unit. The monoblock refrigeration system integrates the compressor, condenser, evaporator, expansion device, and control system into a single compact plug in refrigeration unit, providing a plug and play installation.

How Does a Top Mount Refrigeration Unit Work?

A top mount refrigeration unit is a closed refrigeration cycle. It removes the heat from the upright refrigerator or freezer and maintain in a cold temperature state. The refrigeration components including refrigerator compressor, condenser, evaporator, expansion device, and control system are integrated into a single self-contained refrigeration unit mounted on top of the refrigerator or freezer.

Compression

The Secop refrigerator compressor or Embraco refrigerator compressor draw low-pressure vapor refrigerant from the evaporator and compresses it into a high-pressure, high-temperature refrigerant gas.

Condensation

The hot refrigerant gas flows through the copper tube condenser coil or micro-channel condenser coil, the heat is transferred to the surrounding air by the condenser fan. The refrigerant cools, it condensers into a high-pressure liquid.

Expansion

The liquid refrigerant passes through the capillary, which reduces the pressure and temperature of liquid refrigerant. This creates a cold refrigerant mixture ready to absorb heat from the inside the upright chiller or freezer.

Evaporation

The cold refrigerant enters the evaporator coil, the heat inside the refrigerator or freezer is absorbed by the refrigerant, cooling the storage space. The refrigerant then returns to the compressor, and the cycle repeats continuously.

Applications of Top Mount Refrigeration Units

Top mount refrigeration units are widely used in commercial refrigeration equipment like the upright refrigerator, upright freezer, refrigerated vending machine, refrigerated display cabinet. The drop in refrigeration unit design makes them easy installation and become a popular choice for manufacturers of refrigerators, freezers, display cabinets, and other refrigerated equipment.

Top Mount Refrigeration Unit for Upright Refrigerators

The top mount monoblock cooling units are commonly used in 700L or 1400L stainless steel upright refrigerators and freezers for commercial kitchens for restaurants, hotels, schools and so on. The commercial top mount refrigeration unit provides reliable medium-temperature for the upright refrigerator, reduces installation cost for refrigerator manufacturers. The R290 eco friendly refrigeration unit is also good to our environment.

Top Mount Refrigeration Unit for Upright Freezers

Top mount monoblock freezer unit provides -18 to -22°C low temperature performance for 700L and 1400L stainless steel upright freezers for meat, seafood, ice cream, frozen vegetables, and other temperature-sensitive products. The stainless steel upright freezers with high performance and low maintenance R290 top mount refrigeration unit, are in great demand in commercial kitchens for restaurants, hotels, schools and so on.

Top Mount Refrigeration Unit for Glass Door Display Refrigerators

The top mount refrigerator cooling unit or freezer refrigeration unit can also used in glass door display refrigerators. Because the thermal insulation of glass door display refrigerator is worse than stainless steel upright refrigerator and freezer, so same volume of glass door refrigerator and stainless steel refrigerator, the glass door refrigerator will require a larger cooling capacity compressor and monoblock unit.

Top Mount Refrigeration unit for Floral Display Cooler

The flower coolers are used to display flowers in the flower shops. The air cooled top mount refrigeration unit provides precise temperature 2 to 8°C to slow flower blooming and inhibit bacteria, with soft air flow avoiding strong wind damaging flower petals. The automatic defrosting of monoblock refrigeration unit reduces water accumulation and manual maintenance.

Top Mount Refrigeration unit for Refrigerated Vending Machines

An energy efficient top mount refrigeration unit provides a good solution for refrigerated vending machines because of their plug-and-play design, compact footprint, and reliable cooling performance. They are commonly used for beverage, dairy, and fresh food vending applications. The compact all-in-one design and plug and play installation greatly helps the vending machine manufacturer improve the production efficiency.
