Flexible Size Cyclic Corrosion Chambers

In response to customer demand for larger test chambers to test large samples, in a wide variety of shapes, sizes and weights, Ascott manufacture the CorroFlex, flexible size corrosion chamber. CFX models are cyclic corrosion chambers and can be programmed to create any of 4 distinct climates: salt spray, controlled humidity, air drying and condensation humidity. These climates can be programmed to occur in any sequence for any period of time and repeat automatically. The CFX models also have the ability to automatically open and close their door as part of the test cycle if required, exposing the samples to laboratory ambient conditions as well.

This makes the CorroFlex unique.

Larges range of chamber sizes

Chamber width and depth can be configured in 0.5 m increments. Ideal for testing large or irregularly shaped specimens.

Front-Loading System

Pneumatically operated door opens vertically. Saves space and simplifies loading/unloading.

Safety and Convenience Features

Fresh air purge after testing to prevent salt fog escape. Interior lighting and viewing window for sample monitoring. Corrosion-resistant outer shell and easily accessible brine tank.

Completley customisable chamber

A huge range of accessories available so the customer really gets the chamber they want to suit their application and are not buying any redundancy.

Atomised spray

Easily accessible salt spray atomizer(s) in transparent hard-wearing acrylic, for ease of maintenance.

Plug & Play

The Ascott iP test chambers can be pre-programmed for test standards in the factory, they are very easy to programme and start running.

Touchscreen Controller

Ergonomically positioned control unit for convenient and intuitive operation. Full-colour touchscreen interface with multi-language function and on-screen graphic of chamber temperatures.

Salt solution pump and flow meter

During salt spray testing, the peristaltic pump draws salt water into the chamber from the separate salt solution tank, so avoiding the need for a gravity fed system. This salt water is delivered, via a graduated flowmeter, to the salt spray atomiser inside the chamber. The speed of the pump is fully adjustable by the user, to allow the quantity of salt solution atomised and hence the fall-out rate, to be precisely controlled.

Salt solution reservoir

One 250L salt solution tank is provided for ease of filling and cleaning, one tank for the standard atomiser. All reservoirs incorporate a transparent graduated sight glass for ease of monitoring the solution level inside. During salt spray testing, the salt solution (brine) is drawn from this reservoir by the chamber peristaltic pump, via a primary filter unit which removes any large undissolved salt crystals or other debris.

Chamber heating mats

Silicone rubber encapsulated electrical heating mats are strategically bonded to the outside surfaces of the bottom and sides of the inner working chamber. Here they radiate heat uniformly into the chamber, under the control of the chamber temperature controller. In the salt spray mode of operation, these heaters give the chamber a user adjustable temperature range from ambient to +70°C/158°F.

Test space door

High strength GRP panel front door. Pneumatically operated for ease of opening and closing (door slides up to close and down to open). With centrally located viewing windows for good visual access to chamber interior and test samples when door closed. Solid canopy is fitted to subzero chambers.

Test space

High load capacity (up to 500kg) mesh racking. With test space Illumination.

Immersion Heater

Set into the bottom of the chamber is a water sump containing a corrosion resistant immersion heater. When condensation humidity testing is selected, this sump is automatically filled with water, to a pre-determined level, using water taken from the pressurised supply to which the chamber is connected

Low loading threshold

Low loading threshold for loading and unloading samples into the chamber

Salt spray atomiser

This is a specially designed salt spray atomiser, to guarantee a uniform salt spray fall out which features an integral filter to minimise blockages. During salt spray testing, it is here that the compressed air, delivered via the air saturator, meets the salt solution, to create a fine salt spray (also referred to as 'salt mist' or 'salt fog').

Choose the size to suit your specific application.

As the CorroFlex name implies, these corrosion test chambers offer the user flexibility in specifying the perfect size of chamber to suit their application. The internal width and depth dimensions are variable and can be selected in 0.5m increments.

Installation requirements

Water: Deionized/distilled for topping up air saturator and making salt solution. Air saturator requires a continuous water connection 2.5-5.0 bar (36-73 psi). If air saturator is topped up manually option ACC66 must be ordered.
Air: Clean dry & oil free, 4.0 to 6.0 bar (58-87psi) with 440 Ltrs (15.5cu.ft) per minute flow.
Exhaust: 3m (10ft) exhaust pipe is required which should be terminated outside building (see accessory ACC58).
Drain: 3m (10ft) drain pipe is required which should be terminated into floor level drain (see accessory ACC58).
Operating environment conditions: Indoors, with ambient maintained at +18 to +23°C (+64 to 73°F), 85% max RH (non-condensing).

Product options

Guardian Angel (ACC05)

The Guardian Angel comprises a modular light alarm that can now be fitted to the top of all Ascott iP chambers. When the chamber is in daily use in the laboratory it allows the occupants of the area to see the status of the chamber visually at a distance depending on the colour of the status light:
GREEN: Everything is operating correctly.
AMBER: The chamber has a small problem which will eventually need attention but is still operational.
RED: The chamber operation has been stopped and needs immediate attention.

Heater Blower System (ACC47)

The blower heater assists in increasing and decreasing the chamber temperature and also decreasing humidity process values, which is a requirement of test standards such as JASO M609, CCT-1, and IEC 60068-2-52. This is achieved by introducing ambient air from the local area in which the equipment is located by means of a forced air blower and ball valve. Two alternatives are available: Rapid to 70°C and Ultra-Rapid to 80°C. 

CO2 refrigeration units (ACC29)

A separate free standing air temperature and humidity conditioning unit (ATCU), capable of refrigerating a CCT chamber down to -20°C or -40°C.

Water Fog Humidity (ACC32)

This option provides a second solution line, independent pumping and delivery system and additional reservoir. It is most commonly used with water to create high humidity conditions (95 -100% RH) by spraying water as a fog, this is a requirement of some standards such as SAE J 2334, GMW 14872 & GMW9540.
