SANHUA BRAZED PLATED HEAT EXCHANGER S30A series

The Sanhua S30A series is a mid-capacity Brazed Plate Heat Exchanger (BPHE). Here are its key features and selling points, distilled into short, impactful points:

⭐ S30A Series: Key Features (What it has)

 

Feature Description
Asymmetric Plate Design The plate channels have different volumes for primary/secondary sides.
High Pressure Design (50 bar) Built to withstand high working pressures.
Optimized Fishbone Pattern Engineered chevron pattern for fluid flow turbulence.
Anti-Freezing Design Plate geometry minimizes stagnant flow near freezing-risk areas.
Copper Brazed Standard, durable brazing material (Nickel option available).

SANHUA BPHE S30A Series

KEY POINTS (Benefit) Feature Driving the Benefit
Lower Operating Cost Asymmetric Plate Design Reduces secondary-side pressure drop by approx 25%, significantly cutting pump energy consumption.
Future-Proof Safety High Pressure Design (50 bar) Safely handles new, high-pressure, low-GWP refrigerants (R32, R454B).
High System Efficiency Optimized Fishbone Pattern  Maximizes heat transfer, achieving better system energy ratings (EER/COP) for the final product.
Enhanced Reliability Anti-Freezing Design  Reduces the risk of plate cracking and costly system damage in low-load or defrost cycles.
Compact Mid-Range Power Optimized Design  Delivers approx 5  kW sim 35  kW capacity in a small, lightweight footprint, saving installation space.

Description

🛠️ Sanhua S30A Series: Detailed Technical

The S30A series sits between the S20 and S40A, offering a higher nominal heat transfer area and flow capacity than the S20 while maintaining a compact footprint.

1. Core Specifications

Feature Specification Rationale/Context
Nominal Heat Area 30 /1000 m^2 (Per plate face) This is the meaning of the ’30’ in S30A. It dictates the base size.
Max. Working Pressure 5.0 MPa (50 bar) Standard for high-pressure refrigerants (like R410A, R32, R454B). Designated by ‘H’ in the full model name (e.g., S30A-XXH).
Working Temperature -196^C to +225^C Extremely wide range, enabling use in heat pumps, chillers, and industrial processes.
Brazing Material Copper (Standard) or Nickel (For ammonia/aggressive fluids) Nickel brazing allows the BPHE to handle applications like Ammonia ($R717$) or aggressive brine.
Refrigerant/Fluid R410A, R32, R290, R134a, R448A/R449A, Water/Glycol, Oil Compliant with all major HCFC, HFC, HFO, and Natural (HC) refrigerants.

2. Model Variations (Based on Plate Count N)

The true technical variation comes from the number of plates (N).

Parameter Formula/Estimated Data (Dependent on N)
Max. Plate Count (Nmax) approx 60 \sim 80 Plates
Approx. Weight Base Weight + (Weight per Plate) \cdot N
Maximum Cooling Capacity approx 5 kW  (low  N) to  30 kW(high  N)
Physical Height (H) Increases with N. Height = \text{End Plate Thickness} + (Plate Pitch) \cdot N
Max. Flow Rate (m^3/h) approx 2 m^3/h to 4 m^3/h (Water side)

Below is an illustration of the model range, where N is the number of plates. Any number of plates within this range can constitute a distinct model.

Plate Count (N) Example Model Code (High Pressure) Approximate Capacity (kW) Application
5 S30A-05H approx 4 kW Smallest size, minimal duty, or economizer.
10 S30A-10H approx 8  kW Light commercial heat pump/chiller.
20 S30A-20H approx 15  kW Standard mid-range capacity.
30 S30A-30H approx 22  kW Popular choice for 2-ton chiller/heat pump applications.
40 S30A-40H approx 30  kW Higher capacity commercial system.
50 S30A-50H approx 37  kW Nearing the upper limits for this physical frame size.
60 S30A-60H approx 45  kW Maximum standard capacity.
… S30A-N H Capacity  N Units can go higher (e.g., N=70 or 80) depending on the specific frame length offered by Sanhua.

Additional information

OVERVIEW

The Sanhua S30A series constitutes a range of medium-capacity Brazed Plate Heat Exchangers (BPHEs) designed for demanding HVAC&R applications like commercial heat pumps and chillers, typically handling capacities from approx 4 kW to 45 kW depending on the number of plates (N). Technically, the series is defined by a high design pressure of 5.0 MPa 50 bar), making it fully compatible and safe for use with modern refrigerants such as R32 and R410A. Its primary selling point is operational efficiency, achieved through the patented asymmetric plate design, which significantly reduces pump pressure drop (up to 25%) compared to traditional symmetric plates, thereby lowering running costs. Furthermore, its optimized flow patterns and anti-freezing features ensure high thermal efficiency and enhanced reliability against system failure.
