Condensation Humidity Chamber

Condensation Humidity Chamber

HC Series

Chambers for testing resistance to condensation

NK by NEURTEK’s corrosion test chambers are designed to reproduce, in an accelerated and controlled manner, the environmental conditions that cause the degradation of materials, coatings and components. They are available in two ranges covering the main internationally recognised corrosion test methods:

  • HC Series (NK-HC500 / NK-HC1000): chambers for testing resistance to condensation. They generate a homogeneous saturated humidity environment through the continuous evaporation of water at the base of the chamber.
  • SC Series (NK-SC500 / NK-SC1000): salt spray chambers for long-term corrosion testing (over 240 hours). They incorporate a peristaltic pump, a Venturi nozzle and an external 90-litre brine tank.

 

Both ranges share the same fibreglass-reinforced plastic (FRP) construction, a transparent domed cover with 360° visibility, an intuitive touch screen and a wheeled design with brakes to facilitate installation and movement. Backed by over 40 years’ manufacturing experience.

Application

The HC500 and HC1000 chambers reproduce the condensation humidity conditions required by standards such as ISO 6270-2, DIN 50017, VDA 621-421, ASTM D2247 and BS 3900 Part F2, amongst others. Internal humidity is generated by the continuous evaporation of water from the base tray, which saturates the air inside the chamber.

Samples, at a temperature below the dew point, develop condensation droplets on their surface.

  • Precise, controlled temperature without the need for a fan, thanks to the optimised design for uniform saturation.
  • Tray with automatic refilling, level sensor, temperature probe and safety thermostat.
  • Fixed temperature programming or automatic cycle with defined times.
  • Option to add the ASC-ACC48 cover to also carry out tests in accordance with ISO 6270-1 (HC500 model only).

Features

  • Fibreglass-reinforced plastic (FRP) construction: durable, impact-resistant, chemical-resistant and corrosion-resistant.
  • Dome-shaped, transparent cover with 360° visibility; remains open in a self-supporting position.
  • Touchscreen with an intuitive interface for test configuration and monitoring.
  • Wheels with brakes and forklift pockets: easy to install and move.
  • All connections (electricity, water, air, drainage) centralised to simplify installation.
  • Simple and reliable design, backed by over 40 years’ manufacturing experience.
  • NEURTEK’s own technical service with 48-hour support across the Iberian Peninsula.

FAQS

It is commonly used to evaluate steel, aluminium, galvanised steel, painted components, coated parts, anti-corrosion treatments and components intended for use in aggressive environments.

It means that it has been subjected to an accelerated test for that duration under controlled conditions. However, the hours of exposure do not directly equate to years of service life in real-world conditions.

In a salt spray test, it is advisable to record variables such as chamber temperature, saturator temperature, air pressure, precipitation, pH, water conductivity and the concentration of the salt solution.

Recording these data facilitates the traceability of the test and helps to detect deviations before they affect the results.
