Zhejiang Sanxin Technology Co., Ltd.
浙江三新科技有限公司
Zhejiang Sanxin Technology makes fans for refrigeration, building ventilation and agriculture, and dates its start to 1990. It names production bases in Shaoxing, Huzhou and Guangzhou. For orchards and tea gardens it offers frost-protection fans such as the SX-FSD15-360 (380 V, 3.7 kW, automatic control). Frost fans are sized to the site, so plan a site assessment and an installation proposal with Sanxin.
Sanxin fan ranges and what to define for each
The catalogue covers axial, centrifugal, large industrial ceiling, agricultural and livestock, and frost-protection fans, plus fan rings and panels. Each range calls for different project information in your enquiry. For the livestock and frost-protection ranges, our guide to sizing house fans and frost fans shows which airflow and site details to include.
[1][2]| Range | What to define |
|---|---|
| Refrigeration / ventilation | Airflow and static pressure, how the fan is installed, and noise limits. |
| Agricultural / livestock | The whole air system and its controls, with a stated operating point. |
| Frost protection | Site and crop conditions, the temperature at which the fan should start, and the installed controls. |
| Rings / panels | Drawing, material and the fan assembly they must fit. |
Models and specifications
Quote the exact model, configuration and operating conditions together, and ask the factory to confirm current availability.
Sanxin SX-FSD15-360 Rotating Frost Fan
Catalogue reference: SX-FSD15-360
The Sanxin SX-FSD15-360 is a rotating frost-protection fan for orchards and tea gardens. It has a 3.7 kW motor on a three-phase, four-wire 380 V supply and runs under automatic control. Sanxin states a protected area of 7.5 mu. How much a frost fan protects depends on the site, so start with your frost history and temperature profile, then ask Sanxin for an installation proposal covering tower height, controls, sensors and the conditions behind the area figure.

SX-FSD15-360 frost fan: sizing to the site
The model page lists a three-phase, four-wire 380 V supply, a 3.7 kW motor, automatic control and a stated area of 7.5 mu. It gives no mounting details, sensor or control description, or field conditions. FAO's frost-protection guide explains that a frost fan's benefit depends on local conditions, so one acreage figure cannot fit every site.
For a project, ask Sanxin for the fan, tower and control revision, who installs it, and a crop and site assessment. Each model has its own performance; the catalogue's older SX-FSD55 project belongs to that model.
[1][7]Is this a fit for your project?
Based on the manufacturer's published range.
A good fit for
- Enquiries for axial, centrifugal, livestock and agricultural fans from Sanxin's catalogue.
- Starting a frost-fan site assessment around the SX-FSD15-360 figures.
Confirm in writing before ordering
- Which site and process will make your order, and performance data for the complete system.
- Frost-site suitability, the installed tower and controls, and field response and service records.
National standard work and innovation status
SAMR's page for GB/T 34877.1-2023 lists Sanxin among the organisations that drafted this laboratory method for measuring fan sound power. The standard covers the test method. For noise figures on the SX-FSD15-360, ask Sanxin for a test report.
A Shaoxing tax-authority article dated 28 June 2024 reports Sanxin's university collaboration and innovation status, with patent counts at that date. Sanxin's own undated introduction gives different patent counts. Ask Sanxin for a current patent list if patents matter to your purchase.
[2][5][6]Which site builds your fans
Sanxin's introduction lists three production bases, R&D in Hangzhou and marketing in Hong Kong. It offers OEM/ODM work and mentions an engineering team and in-house mould making. The service page says the fans are produced in-house, and a workshop gallery shows the factory floor, though it gives no machine list or map of which site makes which model.
Ask which site will make and inspect the motor, impeller, frame and controls for your order, which parts are bought in, and how repeat builds are traced. The annual output and staff figures carry no date. Customer and partner logos on the site say nothing about service for your order, so agree support terms in writing.
[2][3][4]From air duty to installed handover
Sanxin's engineering team can help shape an enquiry. Each order still ends with one accepted, installed build.
[1][2][4]Define the duty
Ventilation, refrigeration or frost protection, with the project inputs each needs.
Name the build
Production site, components, revision, and who inspects what.
Agree acceptance
Performance, noise and control records, and a test of the installed fan.
Record service
Maintenance, spare assemblies, delivery date and written warranty and support.

Questions buyers should settle
Does Sanxin's standards work certify its frost fans?
Sanxin helped draft a test method for fan sound power. For the frost fan itself, ask for a model test report.
