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:

ModelQuantities of R600a refrigerant on rating plate [kg[]Minimal volume of room (per fridge) required [m3]
VLS 200A0.050 kg6.25
VLS 300A0.055 kg6.88
VLS 350A0.060 kg7.50
VLS 400A0.063 kg7.88

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:
