Chemical Dosing Pots
Chemical Dosing Pots: Essential Tools for HVAC Water Treatment
Chemical dosing pots are indispensable in maintaining the efficiency and longevity of closed-loop HVAC systems in commercial buildings. They provide a straightforward, cost-effective, and efficient method for introducing treatment chemicals into water circuits, ensuring optimal system performance.
The Importance of Chemical Dosing in HVAC Systems
In closed heating and cooling systems, water quality directly impacts operational efficiency and equipment lifespan. Without proper chemical treatment, systems are susceptible to:
-
Corrosion: Leads to the deterioration of pipes and components, resulting in leaks and system failures.
-
Scaling: Mineral deposits reduce heat transfer efficiency, increasing energy consumption.
-
Microbiological Fouling (Biofouling): The growth of bacteria and algae can obstruct flow and promote corrosion.
Implementing a chemical dosing regimen is crucial to mitigate these issues, as highlighted in BSRIA's BG 50/2021 guide on water treatment for closed heating and cooling systems.
Key Treatment Chemicals and Their Functions
-
Biocides: Control the proliferation of harmful microorganisms, preventing biofouling and maintaining system cleanliness.
-
Corrosion Inhibitors: Form protective films on metal surfaces, safeguarding against oxidative damage and extending equipment life.
-
Glycol: Serves as an antifreeze agent, lowering the freezing point of water to prevent pipework damage in low-temperature environments.
Risks and Costs of Poorly Managed Water Circuits
-
Neglecting proper water treatment can lead to significant operational challenges, including:
-
Reduced Efficiency: Corrosion and scaling diminish heat exchange efficiency, leading to higher energy consumption.
-
Increased Maintenance Costs: System failures due to corrosion or blockages necessitate costly repairs and downtime.
-
Health Hazards: Unchecked microbial growth can pose health risks, potentially leading to building occupant complaints or regulatory violations.
Dosing Pots: A Simple and Effective Solution
-
Dosing pots offer a practical means to introduce treatment chemicals into HVAC systems without the need for shutdowns. Their benefits include:
-
Ease of Use: Allow for the safe and controlled addition of chemicals.
-
Cost-Effectiveness: Eliminate the need for complex dosing equipment, reducing capital expenditure.
-
Versatility: Suitable for both standard and high-pressure systems, accommodating various operational requirements.
-

Installation and Operation Guidelines
-
For optimal performance, dosing pots should be installed across the main flow and return pipework. This ensures rapid chemical feed and uniform distribution within the system. Key steps include:
-
Isolation: Close all valves to safely isolate the pot.
-
Filling: Use the stainless steel tundish to introduce the chemical solution.
-
Air Release: Open the air vent to remove trapped air and ensure proper chemical flow.
-
Injection: Open the necessary valves to deliver the chemical into the system.
