How to Create an Equipment Inventory

You will need a contingency plan for when things go wrong with your equipment. An inventory list helps technicians plan repairs, manage spare parts, and see which locations may need new or additional equipment. Learn how to fill out an equipment inventory, step-by-step. This EPI training video provides knowledge and skills based on WHO guidance (for example, Mid-Level Manager and Immunization in Practice modules) to support routine immunization in the field.

Cold Chain Equipment Production at B Medical Systems

At B Medical Systems, we use the rotational moulding technique to manufacture our vaccine cold chain equipment. The process guarantees products of extreme robustness, high quality and zero corrosion.


B Medical Systems - Total Cost of Ownership

When purchasing cold chain equipment, the Total Cost of Ownership of the units is a major criteria to consider. The TCO reflects all costs associated with owning and operating the units over their 10 year lifespan.

About 100 units were supplied and installed in Kenya during 2012. Evaluated in February 2014. Most of the models were found having a distorted ice-lining which is factory installed with some gel compund into the unit. Most likely, it is suspected that the plastic deformation of the 4 ice lining on the 4 walls, occurred during the storage and transport in the container, during which the units were exposed to temperatures higher than expected. As a result, the ice-lining is not pressed against the wall for efficient cooling. It also causes disturbances to place the baskets properly. This limitation has been informed by UNICEF SD to the manufacturer and the latter is expected to come up with a solution in its new models. This apart, one unit that was observed using a log-tag over 5 months showed excellent temperature control between 2.5 and 4.5 deg. C.

During my time at AMP and principally at LOGIVAC’s demonstration site, I was looking to purchase a dozen BFRV55 for the various health centers that did not have access to grid electricity and that were using obsolete absorption refrigerators. I contacted the manufacturer and was advised by SELF to provide the GPS coordinates of the various sites. Upon reception of these, the manufacturer informed that its equipment may not be best suited for the various sites given the heavy rains and cloud seasons. I have still managed to purchase one BFRV55 and I have installed in a health center that already had another well-functioning refrigerator. The equipment has been installed almost a year ago and is still operating very well despite the heavy rainy seasons that have passed. The temperature is continuously monitored via the 30DTR that has been provided by LOGIVAC. I fully recommend this equipment as it has been working well according to agents on the ground. Furthermore, the manufacturer has been honest in informing about factors that may lead to bad performance of the equipment. However, we have had difficulties using all the available baskets at once and the manufacturer should look at this design feature so that all baskets could be used to store vaccines.

These reviews are based on recent CHAI experience with installing the SunDanzer BFRV 55 DC solar direct drive refrigerator as part of a pilot in southwestern Tanzania. During the experience, a number of points were noted to pass back to the manufacturer to help them improve their designs. These improvements could result in easier and more robust installation processes, thereby allowing for higher likelihoods of successful installations in the field by relatively untrained technicians. As is widely acknowledged, improper installations are the cause of a significant percentage of malfunctioning or broken down refrigerators. Easier installation procedures could help to alleviate this problem. These reviews as well as a host of other points of feedback have already been shared with SunDanzer. The manufacturer has reacted positively and proactively to the feedback, and is already incorporating changes to allow for easier installation of their product. General o The installation videos that are publicly available are very useful. If a USB of these videos and other training materials could be delivered with the unit, it would be very useful. o Visual job aids to assist in routine maintenance and daily usage would be valuable. Tools, materials/parts o The manufacturer’s practice of including all materials (except pole) in one box makes transportation and logistics much easier compared to having a separate box for solar components. This is a huge positive. o The product’s fasteners use the English system of units, all countries where the SDD will be installed use metric sizes. Although the tools are provided with the unit, it would be simpler for all parts to be in metric units if replacement parts need to be procured in country. o Include spare parts of all components needed, especially simple parts that are likely to be easily misplaced (nuts, bolts, screws, etc.). Wiring o This product has extremely simple, “plug and play” wiring. This makes it very easy to connect the solar arrays to the fridge and complete the circuit. Solar array o The East-West facing array configuration is difficult to position on roofs unless the roofs are completely flat. o Could a modified mounting solution be developed for positioning the E-W array at the top convergence of both sides of the roof? This would add greater flexibility to mount on different roof orientations. Note: The manufacturer has accepted this feedback and is working on a solution to this problem. o Constructing the mounting frame of the solar arrays around a pole proved problematic, since some of the fasteners, brackets, nuts, bolts, and screws were confusing to position properly. Need a simpler design and better instructions. Refrigerator o Handles on the side of the refrigerator made carrying it and positioning it in the vaccine storage room easy. o The ON-OFF switch is located in a corner at the back of the fridge. It can be repositioned to be easier to locate.
