Productivity Loss

Equipment downtime can have serious consequences for research and commercial growers in terms of lost productivity and/or lost plants - directly impacting plant growth chamber TCO. As mentioned, equipment malfunctions can disrupt experiments, cause delays, and lead to financial losses. If obsolete parts are not proactively replaced with state-of-the-art equipment you may be in the unenviable position of looking for used parts or refurbished parts with poor reliability. Scheduling urgent repairs can also lead to delays if an authorized service person is not readily available to visit your site on short notice.

Preventative measures such as regular inspections proactive service can minimize downtime. Maintaining a stock of essential spare parts also ensures quick replacements, thus reducing the impact of equipment failures on research and other growing activities.

Extended Warranties & Service Contracts

Purchasing extended warranties and service contracts can provide greater financial predictability and peace of mind. These types of agreements cover costs of repairs and maintenance, reducing unexpected expenses when equipment needs attention.

Extended warranties typically offer comprehensive coverage at a predictable cost, while pay-as-you-go repairs often lead to variable and higher expenses. By ensuring regular maintenance and covering major repair costs, extended warranties help organizations budget more effectively.

Technological Upgrades & Retrofits

Upgrading and retrofitting old plant growth chambers can significantly enhance their efficiency and functionality. While the costs of technological upgrades, such as new controllers or advanced lighting systems, can be substantial, they often lead to long-term savings.

Improved energy efficiency, enhanced environmental control, and extended equipment lifespan are some of the benefits. Successful retrofits have demonstrated improved performance and lower total cost of ownership for plant growth chambers over the long term.
