REFRIGERATOR (Vestfrost VLS350A G1) 127l net, 230V
This article is discontinued and replaced by PCOLREFEVI5 - REFRIGERATOR (Vestfrost VLS354A AC) 127l net, 230V.
Definition
The standard fridge for storage of thermosensitive items such as laboratory material, drugs and vaccines. As Vestfrost stopped producing the MK-series of fridges the Vestfrost VLSA line has been selected as the new standard fridge for MSF.

Instructions for use
Advantages:
- The VLS-line is a so-called ‘green-line' model (less power, more efficient refrigerant and insulation)
- The refrigerant gas R600a (instead of the old standard R134a) is more efficient
- It has a longer hold-over time related to the old MK model, but with less power required (test done according to PQS protocols).
- This model has passed the freeze protection grade A test (see PQS test protocol)
- With the same capacity, it has a significant higher performance and uses less power
- There is a hidden thermostat (knob)
- No automatic alert when power is off
- Stable temperature even when the fridge is full
Remarks:
- Although R600a is a more flammable gas, no clear risks are expected.
- The fridge is PQS approved by the WHO.
- It is expected the field might face more difficulty to exchange the gas/compressor, in case of repairs, in the first few years.
- Globally all fridges shift to R600a, therefore this is expected to improve.
- Rated for use in ambient temperatures above 5°C and below 43°C.
- Note: The compressor will turn off when the room temperature is between 5 - 10°C.
Precautions for Use
Installation:
See manual for installation. In the user manual, it says that you have to install the appliance in a room with a volume of minimal 1m3 per 8g of hydrocarbon refrigerant used in the appliance, which is indicated on the rating plate. The required room volume should be:
Model | Quantities of R600a refrigerant on rating plate [kg[] | Minimal volume of room (per fridge) required [m3] |
VLS 200A | 0.050 kg | 6.25 |
VLS 300A | 0.055 kg | 6.88 |
VLS 350A | 0.060 kg | 7.50 |
VLS 400A | 0.063 kg | 7.88 |
Door seal:
Similar as the old models from Vestfrost, Vestfrost recommends to change the complete lid if the seal is old or broken. However, it stays possible to order the seal (as a spare part) and replace this in the field.
Spare parts:
For all VLS-A models spare parts can be ordered.
Thermostat:
See below the two types of thermostat adjustment on the VLSA fridge, located in the compressor compartment:
