Vindon Stability Storage Rooms provide a large volume controlled environment at a cost

effective price. Modular construction ensures that all panels will pass through a standard

doorway so installation and any future re-location is straightforward. Both the insulating

foam and the refrigerant are CFC free.

All rooms are built and pre-wired at our factory where customers are encouraged to witness

the final testing. Once approved the rooms are dismantled and delivered to site where our

own engineers will re-assemble and commission in the shortest possible time.

The design and build of Environmental Rooms is covered by our ISO 9001 registered quality

system..

Room ShellThe rooms are constructed from self supporting pre-fabricated,

60mm or 100mm thick panels, which lock together by a cam-

lock system. The panels comprise of two steel skins that are

injected with a high pressure, CFC free, polyurethane foam,

thus creating an insulated sandwich panel.

The external face of the panels is finished in white 9002 (RAL)

epoxy coating and the internal skin is finished in grade 316

stainless steel. This provides a surface that will withstand the

specified temperature and humidified environments, will not

rust over time and is easy to clean.

Room dimensions can be altered in size increments of 300mm

with regard to height, width and depth.

Room FlooRThe floor panels are 60mm or 100mm thick, which have been

injected with CFC polyurethane foam. Floors are finished with

a layer of anti-slip polyester.

DooRSThe doors are manufactured from the same materials that are

used on the wall and ceiling panels. The standard size door

opening is 650mm wide and 2000mm high, although larger

dimensions are available. Doors can be either left hand or right

hand hinge, dependent upon customer specification.

The doors are fitted with a key operated lock on the outside

handle of the room. In the event of a person being accidentally

locked inside, an internal push button device can be operated

to allow the person to over-ride the door lock and exit the

room

Shelving SyStemOur rooms incorporate a bespoke shelving system that is

designed to fit around our floor mounted ducting system.

The entire shelving system is manufactured from grade 304

stainless steel. Shelving uprights are securely fastened in

place, providing a strong and stable racking design. Perforatedshelving is supported on rods which sit in holes machined into

the uprights on a 50mm pitch. The height of each shelf can be

adjusted by placing the support rods in the required position of

the holes on the uprights. The shelves are perforated to allow

air to pass through them and onto stored product.

opeRating ConDitionSVindon Scientific stability storage rooms are generally specified

to cover the ICH conditions of 25c/60%RH, 30c/65%RH &

40c/75%RH. Rooms will operate with in the limits of 2c

and 5%RH. This gives users the flexibility of changing the set

point of the room should future requirements ever change. We

can however extend both the temperature and humidity range

based upon customer specification. We also manufacture 5c

cold rooms which use direct refrigeration systems rather than

indirect ones.

inDiReCt ReFRigeRationOur standard ICH - type stability storage rooms use an indirect

refrigeration system to help control the internal temperature of

the room. An ex ternal chiller uses a direct refrigeration system

to cool a tank of water to a specific temperature directly related

to the operating set point of the room. This cooled water isthen pumped to a cooling coil that is located in a stainless steel

plenum at the rear of the room and works together with the

heaters to provide accurate temperature control.

The temperature of the coolant is monitored by a sensor and

controller that switches on the fridge to maintain the required

water temperature.

DuCting SyStemWe control the environment of our stability storage room by

use of a ducting system. This is manufactured from grade

304 stainless steel. The ducting system comprises of a vertical

plenum located at the rear of the room within the corridor. Air

is attracted at high level through this plenum by the fan(s).

That air is then passed down over the cooling coils and over the

heaters to floor mounted horizontal ducts where it passes into

the room through adjustable vents. The floor mounted ducts

are situated beneath our shelving system

ConDenSate pumpThe condensate pump is located in the base of the main control

tower at the front of the room. It collects any condensate that

has dripped off the coiling coils within the room and also

any reject water that has been drained from the humidity

generator. As the water in the pump reaches a float switch, the

pump is activated and the water is sent to drain.

light(S)Stability storage rooms are fitted with a fluorescent light(s)

within the corridor of the room which are activated by an

on/off switch on the face of the main control tower. A neon

light on the switch indicates that the light inside the room is

turned on.

In the event of mains power failure to the room, the light

fitting closest to the door is activated via a battery back up

providing approximately one third of the units normal light

output. This is sufficient to allow a person within the room to

exit safely.

humiDity geneRatoROur stability storage rooms are fitted with a humidity generator

to provide a controlled level of humidity inside the room.

The generator is comprised of a stainless steel tank containing

approximately litre of laboratory grade II water. At the base

of the generator are two ultrasonic transducers that operate

at the resonant frequency of water. When the room requires

humidity, the transducers are energised by the humidity

control circuit causing the water just below the surface to break

into tiny droplets forming a cloud above the surface of the

water. An air supply is taken from the room via flexible tubing

and passed over the sur face of the water, collecting the cloud

of water on the way. This humidified air is then returned to

the room thereby raising the level of humidity inside.

In order to keep the system working to optimum levels, the

water inside the generator is rejected down to the condensate

pump approximately every 6 hours preventing cardboard

spores carried in the air supply from the room settling in the

water and causing the equipment to malfunction.

tempeRatuRe alaRmEach stability storage room is fitted with a temperature alarm

circuit consisting of an independent controller and sensor.

The controller is programmed with the high and low alarm

points for the room. In the event of a temperature alarm, the

controller will activate both audible and visual alarm indicators

on the main control tower and will activate a set of volt free

contacts located within the control tower which can be linked

to a BMS. Once any fault has been cleared, the circuit will re-set

automatically. The audible alarms may be muted.

humiDity alaRmTotally independent alarm system from the temperature alarm

but operates in exactly the same way

paniC alaRmOur stability storage rooms are fitted with a panic alarm circuit

that is activated by one or more push buttons inside the room.

If an operator were to get into difficulty inside the room, they

could press the button which would activate an extremely loud

warning siren and flashing alarm beacon outside the room

to attract the attention of people in the area. In addition, a

further set of volt free contacts will be activated which can be

linked to BMS.

aSSembly & FaCtoRy aCCeptanCe teSt

Stability storage rooms are specifically designed to meetcustomer requirements. Each room is designed and

manufactured at our site in Oldham. Each room is fully

assembled and tested thoroughly at our premises prior to

installation. The room is not dismantled until it has passed ou r

factory qualification requirements. This testing reduces the

site build time significantly, which in turn reduces the impact

our work has on our customers day to day business

We will then make the necessary arrangements to have

the room dismantled, delivered and installed using our own

suitably trained staff.

WaRRantyAll rooms carry a full 12 month parts warranty. After this

period, we offer a preventative maintenance contract or

emergency call out assistance.

Validation

Stability Storage Rooms

At a glance

Vindon Scientific Ltd also offers a comprehensive validation

package both on newly installed equipment and existing

equipment. Our service comprises four main areas:-

is Qfc iQ:- consisting of electrical

safety inspection and testing, mechanical inspection and

component checklists.

or Qfc oQ:- consists of a single-

point calibration, recording of all controller settings and

programming, functional testing o f environmental chambers.IQ & OQ are not required on environmental chambers that are

already in use.

Cr Qfc CQ:- is the calibration of the data

logger and probe set to be used in completion for PQ. The test

probes are placed around the traceable reference probe in the

middle of the chamber and allowed to settle. After a period

of time, readings from the traceable probe are compared

with those from the data logger and test probes. Any error

of the test probes against the traceable probe is corrected via

software on the data logger. After the correction the results are

monitored for a short while to confirm accuracy.

prfrc Qfc pQ:- consist of multiple-point

performance mapping of the environmental chambers and

normally include unloaded, loaded and door open recovery

tests for new equipment or just loaded (as found) testing of

existing environmental chambers. The corrected probes from

the CQ procedure are placed in recorded positions throughout

the chamber and the data is collected of the performance of

the chamber at these points. If out of specification readings

are discovered during the PQ, the validation engineer may

make mechanical or electrical changes to the equipment toresolve the issue.
