DITEK's response to COVID-19

Coronavirus COVID 19

As we all manage the effects of the COVID-19 outbreak on our business and communities, we want to reiterate our commitment to you. DITEK is closely monitoring and assessing the situation, with the health and safety of our employees, customers and partners being our top priority. We continue to follow procedures and guidelines recommended by the CDC, public health departments and local government authorities to ensure the safety of our community.

Our business continues to remain open to provide network and power protection to critical infrastructure including Life Safety, Communications, Information Technology, Public Health, Military and Utilities.

All employees who can work from home are now doing so to minimize risk of exposure and disruption. We have suspended all business travel and face-to-face meetings as well as visitor access to our facilities.

Meetings are now being held virtually via Skype and GoTo-Meeting. We are also hosting live webinars to keep our customers up-to-date on the latest products. We are encouraged by the virtual collaboration and productivity we have seen between our employees and with our customers during this time.

We have implemented work plans and separated shifts to keep our manufacturing lines operational while eliminating risk to our employees as much as possible. Because of this, you may experience slightly longer lead-times on certain products. We thank you in advance for your patience and will keep you updated as more information becomes available.

All of us at DITEK are committed to working closely with you during this unprecedented time. We will communicate any changes in our business as quickly as possible. Should you have questions regarding business continuity, please contact your DITEK Sales Team. We thank you for your continued partnership and wish you good health.
