Measuring tool
Service manifold (gauge set)~ ~4.800–5.500 kr (digital, fx Testo 550s, inkl. moms)Indicative · Buhl & Bønsøe / Lemvigh-Müller · 2026-06
Electronic leak detector~ ~4.000 kr (Testo 316-4 sæt 1, inkl. moms)Indicative · Buhl & Bønsøe / Lemvigh-Müller · 2026-06
Digital refrigerant scale~ ~2.130 kr (Testo 560i, ekskl. moms)Indicative · Buhl & Bønsøe · 2026-06
Vacuum gauge (micron gauge)Verifying that the system has been evacuated to below e.g. 200 micron, so residual moisture and air have been removed before charging.
Machines
2-stage vacuum pumpEvacuating air and moisture from the system before charging with refrigerant, so the system runs cleanly and efficiently.
Refrigerant recovery machine (recovery unit)~ ~3.300 kr (440,99 €, ekskl. evt. told/fragt)Indicative · VEVOR.dk · 2026-07
Hand tools
Pipe cutter for copper pipe~ ~150–500 krIndicative · BilligVVS.dk · 2026-06
Flaring tool (eccentric)Making tight flare joints on refrigeration pipes when connecting e.g. split air-conditioning and heat pump systems.
Pipe bender / bending spring for copper pipeBending refrigeration pipes for neat, kink-free runs during installation, so refrigerant flow is not restricted.
Gas torch kit for brazingHeating pipe joints to brazing temperature when installing and repairing refrigeration circuits — carried out with a welding/thermal cutting certificate and suitable fire protection.
Materials
Copper pipe for refrigeration (soft, coils)The actual refrigerant circuit between indoor and outdoor units on air conditioning and heat pump systems, as well as connections in commercial refrigeration systems.
Armaflex pipe insulation~ ~81–219 kr/m (selvklæbende, efter dimension)Indicative · WATTOO.DK · 2026-06
Nitrogen cylinder with pressure regulatorPressure testing of the refrigerant circuit for leaks and purging during brazing, so the copper pipe doesn't oxidise internally.
Silver/phosphor-copper brazing wire~ ~40-50 kr/stang (kobber-fosfor-loddestang)Indicative · smedebutikken.dk · 2026-07
Safety equipment
Welding/soldering goggles and glovesProtection against flame, sparks and heat when brazing copper pipes on refrigeration circuits — a core task in refrigeration technology.
Equipment
Recovery cylinderStorage of refrigerant recovered from a system with the recovery machine until it can be reused or disposed of correctly under current regulations.
Components
Thermostatic expansion valve (TXV)A core component for metering refrigerant in commercial and industrial systems. Selecting and setting expansion valves based on capacity and pressure drop is a key learning objective of the programme.
Sight glass with moisture indicatorVisual check of the liquid charge (bubbles in the sight glass may indicate undercharging) and of refrigerant dryness during service and fault-finding.
Filter drierProtects the compressor and expansion valve against moisture, acid and dirt — replaced routinely at service and always after a burn-out (motor failure).
Automatik
Pressure switch (high/low pressure cut-out)Protects the compressor against dangerously high pressure and against running in vacuum at too low suction pressure. Part of selecting automation components for system control.
