Dehumidifers

About Dehumidifiers

Dehumidifiers are essential equipment for controlling moisture levels in workshops, storage facilities, construction sites, and domestic spaces throughout the UK. These powerful devices extract excess humidity from the air, preventing condensation, mould growth, and damage to materials, tools, and finished work. Whether you're a tradesperson drying out a newly plastered room, a builder working on a renovation project, or a workshop owner protecting valuable equipment, a reliable dehumidifier is crucial for maintaining optimal working conditions.

MyToolShed.co.uk stocks a comprehensive range of industrial-grade dehumidifiers from trusted brands including Sealey, Draper, and Faithfull, designed to tackle demanding professional applications. From compact portable units suitable for smaller spaces to high-capacity industrial models capable of extracting 50 litres or more per day, our selection includes both standard 240v models and 110v site-safe variants. Many units feature multi-function capabilities, including air conditioning, heating, and air purification for year-round climate control.

Applications

• Plasterers and Decorators: Accelerating drying times after plastering, rendering, or applying water-based paints and finishes
• Builders and General Contractors: Managing moisture in new builds, extensions, and renovation projects to prevent damp-related issues
• Flood Restoration Specialists: Rapidly drying properties following leaks, floods, or burst pipes
• Carpenters and Joiners: Protecting timber stocks and finished joinery from moisture damage in workshops and storage areas
• Vehicle Body Shops: Creating optimal conditions for paint curing and preventing moisture contamination
• Property Maintenance Professionals: Tackling condensation and damp problems in residential and commercial properties
• Warehouse Managers: Protecting stored goods, equipment, and materials from humidity damage
• DIY Enthusiasts: Managing moisture in garages, workshops, and home improvement projects

Choosing The Right Dehumidifiers

Extraction Capacity: Match the dehumidifier's extraction rate to your space size and moisture level. As a general guide, units extracting 10-20 litres per day suit rooms up to 30m², whilst industrial models extracting 50+ litres per day are necessary for larger spaces or faster drying requirements on construction sites.

Operating Temperature: Refrigerant dehumidifiers work best above 15°C, making them ideal for heated spaces and summer site work. For unheated areas or winter use, desiccant models maintain efficiency in temperatures down to 1°C.

Power Supply: Standard 240v models suit workshops and indoor applications with mains power, whilst 110v site-safe variants are essential for construction sites where UK HSE regulations require reduced voltage equipment for safety.

Drainage Options: Larger water collection tanks mean less frequent emptying, but continuous drainage options are invaluable for unattended operation or high-moisture environments where tanks would fill quickly.

Multi-Function Units: Consider combination units from MyToolShed.co.uk offering air conditioning, heating, or air purification if you need year-round climate control for workshops and site offices.

Safety Information

Always position dehumidifiers on stable, level surfaces with adequate clearance around air intake and outlet vents—typically 300-500mm—to prevent overheating and maintain efficient operation. Never operate units in areas with flammable vapours or gases. Regularly check and empty water collection tanks to prevent overflow, and ensure continuous drainage hoses are securely connected. On construction sites, use 110v models connected through properly rated transformers in accordance with HSE guidelines. Inspect power cables before each use, and never operate damaged equipment. Use proper manual handling techniques when moving units with full water tanks.

Frequently Asked Questions

What size dehumidifier do I need for my workshop or site?

Calculate your space volume (length × width × height in metres) and match it to the extraction rate. For moderate humidity in heated spaces, allow 1 litre extraction capacity per 5m³. Double this for severe damp or rapid drying requirements. A 20-litre unit typically suits a single-garage workshop, whilst industrial 50+ litre models are necessary for larger commercial spaces.

Can I leave a dehumidifier running unattended overnight or over weekends?

Yes, most industrial dehumidifiers are designed for continuous operation with built-in safety features including auto-shutoff when tanks are full. For extended unattended use, connect to continuous drainage to eliminate tank capacity limitations. Ensure the unit is on a stable surface and electrical connections are secure.

Do I need 110v or 240v for site work?

UK construction sites typically require 110v reduced-voltage equipment for portable tools and appliances in accordance with HSE guidance, reducing the risk of serious electric shock. If you're working on active building sites, choose 110v models. For fixed workshop installations or domestic use with standard mains power, 240v units are appropriate.
