HVAC System Maintenance
HVAC refers to heating, ventilation, and air conditioning; systems used to control temperature, humidity and air quality in a space.
The global HVAC market is projected to grow to a value of £184 billion by 2029. This growth is accounted for by increasing demand for hybrid cooling, ventilation and heating systems. In addition, a surge in construction, residential and food & drink sectors has also contributed to this growth.
Common units within HVAC systems include boilers, air conditioning units and ducts/vents.
HVAC systems require adequate maintenance in order to function optimally. When HVAC systems do not perform optimally, they pose serious fire risks and can be economically unsustainable. This is due to them containing various integral parts, such as fans, filters, pipework, refrigeration units and electronic sub-systems that are under threat from contaminants such as dirt, moisture, dust and more that can damage system components.
As a result, HVAC manufacturers are looking for the most innovative solutions to maximise the performance and efficiency of their HVAC systems, giving them a competitive edge in this growing market by providing reliable and sustainable systems that limit maintenance and repair.
HVAC Maintenance Tips
Common HVAC maintenance tips include:
- Durable lubrication of moving parts within the system, preventing breakdowns.
- Cleaning debris from all components; improving efficiency.
- Keeping the filters clean or replacing them when clogged.
- Ensuring the electronics are functioning as intended – using electronic protection solutions.
- Tending to leaks immediately, avoiding unexpected downtime.
- Visually inspect the system for any faults.
Top Solutions for HVAC System Lubrication
Lubrication plays a vital role in the effective maintenance of HVAC systems.
By using high-quality lubricants, HVAC manufacturers can ensure:
- Reduction of friction and wear between moving components, increasing efficiency
- Protection from oxidation and corrosion
- Effective temperature regulation and heat dissipation
- Keeping away contaminants from key parts
- Reduced likelihood of breakdowns
- Improved safety and performance
- Reduce noise, squeaks and rattles
- Low-odour and non-toxicity
Krytox™ NRT 8908 is a BAM-certified lubricant designed for use in applications involving gaseous and liquid oxygen. It is applied as a paste and provides excellent long-term lubrication over a wide temperature and pressure range. Due to its unique formulation with special oils and thickeners, it is safe to use in extreme-pressure environments involving oxygen and other oxidising elements. It has an ISO viscosity of 46 and functions optimally within the -40°C to 180°C temperature range.
Molykote 111 is a lubricant and sealant with excellent resistance to most chemicals and water. It provides superb lubrication for pressure connection and control valves and valves for water softeners and faucets. It prevents o-rings from sticking to metal and is resistant to weather conditions and water stripping. It functions optimally within a wide working temperature range of -40ºC to 200ºC.
Molykote 3400 A is a dry heat cure lubricant for metal/metal combinations involving slow to medium-fast movements and medium to heavy loads. It has successfully been used in locks, switches, ventilation controls and servo mechanisms.
Molykote 5 Compound is a dielectric compound used as a lubricant for high-current switches, insulators and bushings. It prevents arcing, flashovers and the formation of conductive paths. It is non-conductive, water-repellant and long-lasting.
Molykote 55 O-Ring Grease is a silicone lubricating grease for O-rings. It acts as a dynamic lubricant between rubber and metal parts and is compatible with many plastics.
