Ensuring Uninterrupted Safety in Cold Climates with the Bohua BH30-5012A Auto-Drain Anti-Freeze Station

How our self-draining technology solves the critical challenge of winterizing emergency equipment.

Introduction: The Critical Challenge

In industries where hazardous materials are handled, emergency showers and eyewash stations are non-negotiable safeguards. However, in cold climates or unheated facilities, a standard safety station presents a severe risk: water lines can freeze, rendering the equipment useless at the moment it is desperately needed. Facilities face a dilemma—shut down and winterize equipment (creating a safety gap) or risk catastrophic pipe bursts and non-functional stations.

The Bohua Solution: The BH30-5012A Auto-Drain Anti-Freeze System

Shanghai Bohua engineered the Model BH30-5012A to eliminate this vulnerability. This is not just a combined shower and eyewash; it is an intelligent, climate-resilient safety system. Its core innovation is the fully automatic draining mechanism that evacuates all water from the standpipe and exposed lines immediately after use, preventing any residual water from freezing and damaging the unit.

Key Features & Technical Advantages:

· Patented Anti-Freeze Core: The system’s automatic drain ensures instantaneous dry-pipe conditions post-use, guaranteeing 24/7/365 readiness and eliminating freeze-related maintenance costs.
· ANSI Z358.1-2014 Compliance Guaranteed: Engineered to meet and exceed the standard. Delivers water within 1 second of activation, with precise flow rates (Shower: 120-180 L/min, Eyewash: 12-18 L/min) and correct spray patterns (508mm diameter at 1524mm height).
· Premium Corrosion-Resistant Construction: Offered in 304 or 316 Stainless Steel, the unit is built to withstand corrosive industrial environments, coastal air, and harsh weather, ensuring a long service life.

· Ergonomic & User-Centric Design:
  · Optimal Heights: Eyewash (1050mm) and shower head (2100mm) positioned for immediate, comfortable access during an emergency.
  · High-Visibility Safety Sign: Luminous aluminum alloy indicator ensures the station can be located quickly, even in low-light or smoky conditions.
  · Reliable Components: Two-piece ball valve for smooth, stay-open operation; adjustable flow control; and soft rubber dust covers to protect outlets.
