Sanhua SH035 Microchannel Condenser — 2 fans Ø200 mm, MCHE

Sanhua SH035 is a microchannel condenser (MCHE — Microchannel Heat Exchanger) developed specifically for commercial refrigeration systems. The dual-fan aluminum coil design replaces traditional tube-and-fin condensers, offering higher efficiency with smaller dimensions, lower weight, and reduced refrigerant charge. With no galvanic corrosion risk (all-aluminum coil) and easy cleaning, it is a reliable solution for refrigerated furniture, display cases, and cold cabinets.

Key features and benefits

• Full-aluminum microchannel coil — no galvanic corrosion means long-lasting, stable performance without exchanger degradation.
• 2 fans Ø200 mm, airflow 500 m3/h — strong air circulation ensures effective condensation even at high ambient temperatures.
• Condensing capacity up to 1935 W (R404A, standard conditions: T_c=47°C, T_amb=32°C) — compact size relative to heat transfer power.
• Low internal volume — reduced refrigerant charge means lower service costs and compliance with environmental requirements (especially important with R290).
• DC51D+Z housing and copper inlet/outlet pipes Ø8 mm — robust construction ready for installation, with direct connection to existing copper systems without adapters.
• Compatible with R290, R404A, R448A, R449A — ready for low-GWP refrigerants and next-generation HFOs without replacing the condenser.
• Max operating pressure 4.5 MPa (45 bar) — safe operation even in high-pressure systems with R290.
• FPI 12.7 — optimized fin spacing minimizes dust buildup and simplifies maintenance.

Application

The SH035 condenser is designed for medium-power commercial refrigeration equipment: refrigerated furniture, display cases, cold cabinets, and small condensing units. With compatibility for natural refrigerant R290 (propane), it is well suited for new projects meeting F-gas requirements and eco-design directives.

FAQ — frequently asked questions

Which refrigerants does the Sanhua SH035 condenser support?

The SH035 is compatible with R290 (propane — a natural low-GWP refrigerant), R404A, and HFO refrigerants supported by the Sanhua MCHE platform, including R448A and R449A. This makes it suitable both for modernizing existing systems and for new projects that comply with F-gas regulations.

What are the overall dimensions of SH035 (with housing)?

The total height is 242 mm, the length with bracket is 694 mm, and the depth (thickness) is 108 mm. The coil itself measures H=237 mm × B=650 mm.

What is the condensing capacity of SH035 when operating with R404A?

Under standard measurement conditions (T_c=47°C, T_amb=32°C, T_{gas in}=90°C, SC=1 K, RH=50%) and an air velocity of 1.0 m/s, the capacity is 2 101 W. Full data for all air velocities are shown in the table above.

How should SH035 be connected to the refrigeration system — what type of fittings?

Both the inlet and outlet have an outside diameter of O8 mm and are made of copper, allowing direct brazing or connection to standard copper refrigeration installations without adapters.

What is the maximum operating pressure of SH035?

The maximum operating pressure (PS) is 4.5 MPa (45 bar), enabling safe operation even with R290, which typically works at higher pressures than traditional HFC refrigerants.

Why choose a microchannel condenser instead of a traditional tube-and-fin condenser?

MCHE technology offers a higher heat transfer coefficient, smaller dimensions and weight, lower refrigerant charge (internal volume only 0.1994 l), and a full-aluminum construction that resists galvanic corrosion. This means lower refrigerant costs, simpler logistics, and longer equipment life.

How many fans does SH035 have and what is the total airflow?

The SH035 is equipped with 2 fans with a diameter of O200 mm, providing a total airflow of 500 m3/h (data according to the manufacturer leaflet).
