Flamco Dirt & Air Separation Solutions for Chiller (Cooling) and Boiler (Heating) Systems

Introduction

In HVAC systems, properly treated water is a decisive factor for long-term efficiency and reliability. Systems where water is fully deaerated and free from dirt particles consume less energy, generate less noise, and operate with significantly extended service life.

As a trusted distributor, PGTECH delivers sustainable water treatment solutions, including advanced dirt and air separators for Chiller (Cooling) and Boiler (Heating) systems from Flamco—a globally recognized Dutch manufacturer. Flamco products are engineered based on proven physical principles combined with innovative technologies to ensure optimal HVAC system performance.

Among these, the Flamco Smart series—especially Flamcovent Clean Smart—offers a breakthrough solution capable of simultaneously removing micro air bubbles and dirt particles from hydronic systems.

Overview of Flamco Smart Dirt & Air Separation Technology

The latest Flamco product lines—Flamcovent, Flamco Clean, and Flamcovent Clean Smart—are designed to eliminate even the smallest microbubbles and dirt particles down to 4 microns (4 µm) from heating and cooling systems.

Key advantages include:

• Up to 60% higher performance compared to conventional separators
• Extremely low flow resistance, maximizing energy efficiency
• Standard flow velocity up to 3 m/s
• Consistent performance throughout the product lifecycle
• Minimal maintenance requirements

These solutions effectively protect pumps and system components, prevent corrosion and scaling, reduce maintenance frequency, limit chemical usage, and significantly lower operational costs. As a result, overall HVAC system efficiency is improved while extending equipment lifespan.

Flamco Product Range for Dirt & Air Separation

1. Flamcovent Clean Smart – Combined Dirt & Air Separator

The Flamcovent Clean Smart is a next-generation steel combined separator designed for Chiller and Boiler systems. It efficiently removes both dirt particles and micro air bubbles down to 4 µm.

Key features:

• Up to 60% more efficient than conventional air separators
• Operating pressure up to 16 bar
• Temperature range: -10°C to 120°C
• Compatible with glycol solutions up to 50%
• Integrated flow tube enhances microbubble separation efficiency

The device uses an advanced internal structure to direct microbubbles into an air chamber, where they are discharged via an automatic air vent.

Additionally, it integrates 25 high-performance permanent magnets:

• Magnetic strength: 13,000 Gauss (1.3 Tesla) per magnet
• Removes:
  • ≥15% of 70 µm microbubbles per cycle
  • ≥35% of 150 µm dirt particles per cycle
• Separation efficiency up to 40% per cycle

Available sizes:

• Flanged: DN50 to DN600
• Threaded (brass): DN20 to DN50
• Pressure ratings: PN10, PN16, PN25
• Manufactured according to Pressure Equipment Directive 2014/68/EU

• Converting open systems into closed-loop systems

Technical specifications:

• Max pressure: 16 bar
• Temperature range: -10°C to 120°C
• Glycol compatibility up to 50%

Like the combined model, it features 25 powerful magnets ensuring high-efficiency dirt removal and stable long-term performance.

3. Flamcovent Smart – Air Separator

The Flamcovent Smart is engineered to remove micro air bubbles from system water, improving circulation and thermal efficiency.

Key design elements:

• Automatic air vent with emergency shut-off
• Cone-shaped air chamber for optimal separation
• Float-operated venting mechanism
• Surface debris discharge valve

This smart air separation technology delivers over 60% higher efficiency compared to conventional air separators.

Benefits:

• Eliminates air-related issues such as noise and corrosion
• Improves pump performance
• Enhances system heat transfer efficiency
• Reduces maintenance and operational costs

Technical specifications:

• Pressure: up to 16 bar
• Temperature: -10°C to 120°C
• Glycol compatibility up to 50%

Available in flanged sizes DN50–DN600 and threaded DN20–DN50, compliant with European PED 2014/68/EU standards.

Why Dirt & Air Separation Is Essential in HVAC Systems?

Industry experts and manufacturers agree that installing dirt and air separation solutions can:

• Reduce energy consumption by 12%–25%
• Cut total operating costs by up to 55% annually

In Europe and the United States, these devices are considered mandatory components in modern HVAC system design. In Vietnam, they are increasingly specified in consulting and design packages for large-scale projects.

Depending on system requirements, engineers may choose:

• Combined dirt & air separators
• Air separators only
• Dirt separators only
• Or a combination of both devices

However, best practice strongly recommends installing both dirt and air separation systems to maximize performance, minimize maintenance, and achieve optimal lifecycle cost efficiency.
