JXF Stainless Steel Control Box

Are you still troubled by the fact that the distribution box rusts and even breaks down due to moisture within just two years? Ordinary cold-rolled steel often proves inadequate when exposed to salt fog from the seaside, acidic and alkaline gases from chemical plants, or high humidity from fish farming. This not only damages the appearance of the box but also poses a serious threat to the safety of the internal electrical components, easily causing short circuit accidents.

The JXF Stainless Steel Control Box from Junray Electrical is specifically designed to address this industry issue. We have abandoned the traditional ordinary steel and opted for 304 food-grade stainless steel. This material has extremely strong corrosion resistance and can perfectly withstand the erosion of salt fog, acidic and alkaline gases, and humid environments. No matter where your project is located, this box can ensure the safety of the internal components and completely eliminate your worries.

Core advantage

The core competitiveness of JXF Stainless Steel Control Box lies in its outstanding material and structural design:

Superior corrosion resistance, extended lifespan: Using 304 food-grade stainless steel sheets, its corrosion resistance is more than three times that of ordinary cold-rolled steel. In extreme environments such as on the coast or in chemical workshops, ordinary boxes may already be covered in rust, while our product remains shiny and new, with a lifespan of over ten years.

Fully sealed waterproof: We have adopted a fully sealed structural design, combined with the waterproof properties of stainless steel itself, achieving a high protection level of IP54 (optional). Whether in the outdoor with torrential rain or in the aquatic workshop with water vapor, it can effectively prevent rainwater and water vapor from entering, ensuring internal dryness.

Hygienic and easy to clean: The stainless steel surface is smooth, not prone to oil stains and dust, and easy to clean. This makes it not only suitable for industrial environments but also perfectly meets the high hygiene standards required by food workshops and pharmaceutical workshops.

Retrofit Project Overview

I. Project Summary

This project involves the construction of a small, integrated sewage treatment station for a township. The facility is equipped with submersible sewage pumps, recirculation pumps, aeration blowers, chemical dosing units, and automatic liquid-level control systems. All control cabinets are installed outdoors—positioned beside open-air tanks and green belts—where they are constantly exposed to harsh conditions, including high humidity, acidic and alkaline vapors, rain, intense sunlight, insects, and dust.

The original standard powder-coated iron control cabinets were highly susceptible to rust and corrosion in this environment; issues such as seized locks, peeling paint, and water ingress led to internal component short circuits, control system failures, and equipment malfunctions. For this project, all units were replaced with 304 stainless steel JXF-series control cabinets. These serve as terminal control units for local equipment start/stop operations, local automation, signal acquisition, and on-site protection, ensuring stable, unattended operation of the sewage station throughout the year.

II. Issues Prior to Retrofit

High susceptibility to corrosion and rust: The station’s environment features high humidity and heavy acidic/alkaline mist; iron cabinets would peel, rust, and develop holes at the base within just six months, severely compromising equipment safety.

Inadequate waterproofing and dustproofing: Standard cabinets offered poor sealing, allowing rainwater ingress and condensation accumulation, which caused contactor adhesion, terminal oxidation, and circuit short circuits.

Locks and hinges prone to seizing and damage: Severe outdoor weathering and corrosion made it impossible to open cabinets for maintenance later on, creating significant operational challenges.

Cabinet deformation and loss of protection: Prolonged exposure to sun and rain caused cabinet deformation and door misalignment, rendering dustproof and waterproof measures ineffective.

High equipment failure rate: The harsh internal cabinet environment led to frequent component failures and malfunctions in pump and blower start/stop operations, hindering the station's ability to meet sewage treatment standards.

III. Equipment Configuration Plan

To address the sewage station's operating conditions—characterized by high outdoor humidity, corrosiveness, and unattended operation—stainless steel JXF-series control cabinets were selected for all local control applications. These feature a standardized wall-mounted design and incorporate functions such as start/stop control, overload and short-circuit protection, local/remote switching, signal feedback, and interlocked liquid-level control.
